Don't let an injury sideline you.

Symptoms

For most people, cervical spondylosis causes no symptoms. When symptoms do occur, they typically include pain and stiffness in the neck.

Sometimes, cervical spondylosis results in a narrowing of the space needed by the spinal cord and the nerve roots that pass through the spine to the rest of your body. If the spinal cord or nerve roots become pinched, you might experience:

• Tingling, numbness and weakness in your arms, hands, legs or feet
• Lack of coordination and difficulty walking
• Loss of bladder or bowel control

When to see a doctor

Seek medical attention if you notice a sudden onset of numbness or weakness, or loss of bladder or bowel control.

Symptoms

Most herniated disks occur in the lower back, although they can also occur in the neck. Signs and symptoms depend on where the disk is situated and whether the disk is pressing on a nerve. They usually affect one side of the body.

• Arm or leg pain. If your herniated disk is in your lower back, you'll typically feel the most pain in your buttocks, thigh and calf. You might have pain in part of the foot, as well. If your herniated disk is in your neck, you'll typically feel the most pain in your shoulder and arm. This pain might shoot into your arm or leg when you cough, sneeze or move into certain positions. Pain is often described as sharp or burning.
• Numbness or tingling. People who have a herniated disk often have radiating numbness or tingling in the body part served by the affected nerves.
• Weakness. Muscles served by the affected nerves tend to weaken. This can cause you to stumble, or affect your ability to lift or hold items.

You can have a herniated disk without symptoms. You might not know you have it unless it shows up on a spinal image.

When to see a doctor

Seek medical attention if your neck or back pain travels down your arm or leg, or if you also have numbness, tingling or weakness.

Symptoms

Many people have evidence of spinal stenosis on an MRI or CT scan but may not have symptoms. When they do occur, they often start gradually and worsen over time. Symptoms vary depending on the location of the stenosis and which nerves are affected.

In the neck (cervical spine)

• Numbness or tingling in a hand, arm, foot or leg
• Weakness in a hand, arm, foot or leg
• Problems with walking and balance
• Neck pain In severe cases, bowel or bladder dysfunction (urinary urgency and incontinence)

In the lower back (lumbar spine)

• Numbness or tingling in a foot or leg
• Weakness in a foot or leg
• Pain or cramping in one or both legs when you stand for long periods of time or when you walk, which usually eases when you bend forward or sit
• Back pain

When to see a doctor

See your doctor if you have any of the symptoms listed.

Symptoms

Signs and symptoms include:

• Pain that's often worsened by holding your head in one place for long periods, such as when driving or working at a computer
• Muscle tightness and spasms
• Decreased ability to move your head
• Headache

When to see a doctor

Most neck pain improves gradually with home treatment. If not, see your doctor.

Seek immediate care if severe neck pain results from an injury, such as a motor vehicle accident, diving accident or fall.

Contact a doctor if your neck pain:

• Is severe
• Persists for several days without relief
• Spreads down arms or legs
• Is accompanied by headache, numbness, weakness or tingling

Symptoms

If you have bursitis, the affected joint might:

• Feel achy or stiff
• Hurt more when you move it or press on it
• Look swollen and red

When to see a doctor

Consult your doctor if you have:

• Disabling joint pain
• Sudden inability to move a joint
• Excessive swelling, redness, bruising or a rash in the affected area
• Sharp or shooting pain, especially when you exercise or exert yourself
• A fever

Symptoms

Frozen shoulder typically develops slowly, and in three stages. Each stage can last a number of months.

• Freezing stage. Any movement of your shoulder causes pain, and your shoulder's range of motion starts to become limited.
• Frozen stage. Pain may begin to diminish during this stage. However, your shoulder becomes stiffer, and using it becomes more difficult.
• Thawing stage. The range of motion in your shoulder begins to improve.

For some people, the pain worsens at night, sometimes disrupting sleep.

Symptoms

The pain associated with a rotator cuff injury may:

• Be described as a dull ache deep in the shoulder
• Disturb sleep
• Make it difficult to comb your hair or reach behind your back
• Be accompanied by arm weakness

When to see a doctor

Shoulder pain that is short-lived may be evaluated by your family doctor. See your doctor right away if you have immediate weakness in your arm after an injury.

Symptoms

Signs and symptoms of tendinitis tend to occur at the point where a tendon attaches to a bone and typically include:

• Pain often described as a dull ache, especially when moving the affected limb or joint
• Tenderness
• Mild swelling

When to see a doctor

Most cases of tendinitis respond to self-care measures. See your doctor if your signs and symptoms persist and interfere with your daily activities for more than a few days.

Symptoms

If you have bursitis, the affected joint might:

• Feel achy or stiff
• Hurt more when you move it or press on it

Symptoms

Golfer's elbow is characterized by:

• Pain and tenderness. Usually felt on the inner side of your elbow, the pain sometimes extends along the inner side of your forearm. Pain typically worsens with certain movements.
• Stiffness. Your elbow may feel stiff, and making a fist might hurt.
• Weakness. You may have weakness in your hands and wrists.
• Numbness or tingling. These sensations might radiate into one or more fingers — usually the ring and little fingers.

The pain of golfer's elbow can come on suddenly or gradually. The pain might worsen with certain movements, such as swinging a golf club.

When to see a doctor

Consult your doctor if rest, ice and over-the-counter pain relievers don't ease your elbow pain and tenderness. Seek immediate care if:

• Your elbow is hot and inflamed, and you have a fever
• You can't bend your elbow
• Your elbow looks deformed
• You suspect you've broken a bone

Symptoms

The pain associated with tennis elbow may radiate from the outside of your elbow into your forearm and wrist. Pain and weakness may make it difficult to:

• Shake hands or grip an object
• Turn a doorknob
• Hold a coffee cup

When to see a doctor

Talk to your doctor if self-care steps such as rest, ice and use of over-the-counter pain relievers don't ease your elbow pain and tenderness.

Symptoms

The lumps associated with ganglion cysts can be characterized by:

• Location. Ganglion cysts most commonly develop along the tendons or joints of your wrists or hands. The next most common locations are the ankles and feet. These cysts can occur near other joints as well.
• Shape and size. Ganglion cysts are round or oval and usually measure less than an inch (2.5 centimeters) in diameter. Some are so small that they can't be felt. The size of a cyst can fluctuate, often getting larger when you use that joint for repetitive motions.
• Pain. Ganglion cysts usually are painless. But if a cyst presses on a nerve — even if the cyst is too small to form a noticeable lump — it can cause pain, tingling, numbness or muscle weakness.

When to see a doctor

See your doctor if you experience a noticeable lump or pain in your wrist, hand, ankle or foot. He or she can make a diagnosis and determine whether you need treatment.

Symptoms

Signs and symptoms of tendinitis tend to occur at the point where a tendon attaches to a bone and typically include:

Symptoms

Signs and symptoms of trigger finger may progress from mild to severe and include:

• Finger stiffness, particularly in the morning
• A popping or clicking sensation as you move your finger
• Tenderness or a bump (nodule) in the palm at the base of the affected finger
• Finger catching or locking in a bent position, which suddenly pops straight
• Finger locked in a bent position, which you are unable to straighten

Trigger finger can affect any finger, including the thumb. More than one finger may be affected at a time, and both hands might be involved. Triggering is usually more pronounced in the morning, while firmly grasping an object or when straightening your finger.

When to see a doctor

Seek immediate medical care if your finger joint is hot and inflamed, as these signs may indicate an infection.

If you have any stiffness, catching, numbness or pain in a finger joint, or if you can't straighten or bend a finger, make an appointment with your doctor.

Symptoms

Back pain can range from a muscle aching to a shooting, burning or stabbing sensation. In addition, the pain may radiate down your leg or worsen with bending, twisting, lifting, standing or walking.

When to see a doctor

Most back pain gradually improves with home treatment and self-care, usually within a few weeks. Contact your doctor if your back pain:

• Persists past a few weeks
• Is severe and doesn't improve with rest
• Spreads down one or both legs, especially if the pain extends below the knee
• Causes weakness, numbness or tingling in one or both legs
• Is accompanied by unexplained weight loss

• A fever

Hip impingement occurs when the ball and socket of the hip joint don't fit together properly. The restricted motion damages cartilage and can cause pain and arthritis in young adults.

In some cases, the ball is too misshapen to fit properly into the socket. Sometimes, the exterior edge of the socket extends to the point that it covers too much of the ball. Hip impingement also can be caused by a combination of these two problems.

Most people with hip impingement experience pain in the groin area during or after flexing the hip, as when running, jumping or sitting for a long time. You may also have difficulty flexing your hip beyond a right angle.

Surgery may be required to prevent further hip injury.

Symptoms

Signs and symptoms of tendinitis tend to occur at the point where a tendon attaches to a bone and typically include:

• Pain often described as a dull ache, especially when moving the affected limb or joint
• Tenderness
• Mild swelling

When to see a doctor

Most cases of tendinitis respond to self-care measures. See your doctor if your signs and symptoms persist and interfere with your daily activities for more than a few days.

Symptoms

In some cases, a Baker's cyst causes no pain, and you may not notice it. If you do have signs and symptoms, they might include:

• Swelling behind your knee, and sometimes in your leg
• Knee pain
• Stiffness and inability to fully flex the knee

Your symptoms may be worse after you've been active or if you've been standing for a long time.

When to see a doctor

If you have pain and swelling behind your knee, see your doctor. Though unlikely, a bulge behind your knee may be a sign of a condition more serious than a fluid-filled cyst.

This occurs when the tough band of tissue that extends from the outside of your hip to the outside of your knee (iliotibial band) becomes so tight that it rubs against the outer portion of your femur. Distance runners and cyclists are especially susceptible to iliotibial band syndrome.

Symptoms

If you've torn your meniscus, you might have the following signs and symptoms in your knee:

• A popping sensation
• Swelling or stiffness
• Pain, especially when twisting or rotating your knee
• Difficulty straightening your knee fully
• Feeling as though your knee is locked in place when you try to move it
• Feeling of your knee giving way

When to see a doctor

Contact your doctor if your knee is painful or swollen, or if you can't move your knee in the usual ways.

Symptoms

Open pop-up dialog box Signs and symptoms will vary, depending on the severity of the injury, and may include:

• Pain
• Swelling
• Bruising
• Limited ability to move the affected joint
• Hearing or feeling a "pop" in your joint at the time of injury

When to see the doctor

Mild sprains can be treated at home. But the injuries that cause sprains can also cause serious injuries, such as fractures. You should see a doctor if you:

• Can't move or bear weight on the affected joint
• Have pain directly over the bones of an injured joint
• Have numbness in any part of the injured area

Symptoms

Symptoms

Plantar fasciitis typically causes a stabbing pain in the bottom of your foot near the heel. The pain is usually the worst with the first few steps after awakening, although it can also be triggered by long periods of standing or when you get up after sitting. The pain is usually worse after exercise, not during it.

Symptoms

If you have shin splints, you might notice tenderness, soreness or pain along the inner side of your shinbone and mild swelling in your lower leg. At first, the pain might stop when you stop exercising. Eventually, however, the pain can be continuous and might progress to a stress reaction or stress fracture.

When to see a doctor

Consult your doctor if rest, ice and over-the-counter pain relievers don't ease your shin pain.

Symptoms

Signs and symptoms will vary, depending on the severity of the injury, and may include:

• Pain
• Swelling
• Bruising
• Limited ability to move the affected joint
• Hearing or feeling a "pop" in your joint at the time of injury

The bones that make up your spine (vertebrae) can weaken to the point that they crumple, which may result in back pain, lost height and a hunched posture.

Symptoms

At first, you might barely notice the pain associated with a stress fracture, but it tends to worsen with time. The tenderness usually starts at a specific spot and decreases during rest. You might have swelling around the painful area.

When to see a doctor

Contact your doctor if your pain becomes severe or if you feel pain even when resting or at night.

The most common signs and symptoms of arthritis involve the joints. Depending on the type of arthritis you have, your signs and symptoms may include:

• Pain
• Stiffness
• Swelling
• Redness
• Decreased range of motion

Symptoms

Carpal tunnel syndrome symptoms usually start gradually and include:

• Tingling or numbness. You may notice tingling and numbness in your fingers or hand. Usually the thumb and index, middle or ring fingers are affected, but not your little finger. You might feel a sensation like an electric shock in these fingers.
  The sensation may travel from your wrist up your arm. These symptoms often occur while holding a steering wheel, phone or newspaper, or may wake you from sleep.
  Many people "shake out" their hands to try to relieve their symptoms. The numb feeling may become constant over time.
• Weakness. You may experience weakness in your hand and drop objects. This may be due to the numbness in your hand or weakness of the thumb's pinching muscles, which are also controlled by the median nerve.

When to see a doctor

See your doctor if you have signs and symptoms of carpal tunnel syndrome that interfere with your normal activities and sleep patterns. Permanent nerve and muscle damage can occur without treatment.

Symptoms

Pain that radiates from your lower (lumbar) spine to your buttock and down the back of your leg is the hallmark of sciatica. You might feel the discomfort almost anywhere along the nerve pathway, but it's especially likely to follow a path from your low back to your buttock and the back of your thigh and calf.

The pain can vary widely, from a mild ache to a sharp, burning sensation or excruciating pain. Sometimes it can feel like a jolt or electric shock. It can be worse when you cough or sneeze, and prolonged sitting can aggravate symptoms. Usually only one side of your body is affected.

Some people also have numbness, tingling or muscle weakness in the affected leg or foot. You might have pain in one part of your leg and numbness in another part.

When to see a doctor

Mild sciatica usually goes away over time. Call your doctor if self-care measures fail to ease your symptoms or if your pain lasts longer than a week, is severe or becomes progressively worse. Get immediate medical care if:

• You have sudden, severe pain in your low back or leg and numbness or muscle weakness in your leg
• The pain follows a violent injury, such as a traffic accident
• You have trouble controlling your bowels or bladder
