Cubital tunnel syndrome and radial tunnel syndrome aren't as familiar as their better-known relative -- carpal tunnel syndrome -- but they also can cause severe pain, numbness, tingling, and muscle weakness in the hands and arms.
The common cause of all these nerve compression syndromes is increased pressure -- usually from bone or connective tissue -- on a nerve in the wrist, arm, or elbow. In most cases, cubital tunnel syndrome and radial tunnel syndrome can be managed with conservative treatments...
De Quervain's tendinitis. This is also known as de Quervain's tendinosis. It causes pain on the thumb side of the wrist.
The pain may develop gradually or suddenly. It can travel the length of the thumb and up the forearm. If you have de Quervain's tendinitis, movements that can be painful include:
making a fist
grasping or holding objects
turning the wrist
The pain results from swelling of the wrist tendons at the base of the thumb, which is caused by irritation or inflammation. Repetitive activities and overuse are often responsible for the onset of de Quervain's.
New mothers are at high risk because of the awkward position in which they hold their baby and their fluctuating hormones. Wrist fractures can also increase your risk of de Quervain's. Pain relief treatments include:
wearing a splint to rest the thumb and wrist
Surgery is an option if symptoms remain severe after other treatments have been tried.
Carpal tunnel syndrome. This is one of the most common nerve disorders. It affects about 4 million to 10 million Americans.
Carpal tunnel syndrome causes pain in the:
palm and some fingers of the hand
Often the pain is worse at night than during the day. Carpal tunnel syndrome can also cause:
These symptoms can be particularly noticed in the thumb, index finger, and middle finger. This can make it hard to grip objects.
The discomfort occurs when swelling presses against the median nerve. The median nerve controls sensation and muscle impulses in the thumb and fingers (except for the pinkie finger).
The median nerve passes through the carpal tunnel. The carpal tunnel is a structure made up of bones and connective tissues that is located at the base of the hand. It is in this narrow space that the median nerve is pinched by inflamed or irritated tendons or other swelling.
Common treatments include:
resting the hand and wrist
anti-inflammatory or analgesic painkillers
Surgery may be suggested if symptoms persist for six months or more.
Fractures. A fracture, or a break in a bone, can cause a great deal of hand pain. Besides pain, after a fracture you may have:
loss of movement
If you have fractured a finger, for example, you may be unable to move it fully. You might also notice that the injured finger is swollen and in some cases slightly shorter than normal.
