Repetitive strain injuries are very common in the wrist, and usually found in office workers who spend a great deal of time on a keyboard. This usually shows as a tendonitis, which is an inflammation of the tendon in one of the forearm/wrist muscles.
Carpal tunnel syndrome is a compression of a nerve as it goes through the wrist. This often gives pins and needles into the fingers. This condition is very often linked to neck problems; indeed the symptoms may be coming from a trapped nerve in the neck and not the wrist at all.
Pain in the fingers or joints of the hands and wrist may be caused by osteoarthritis or rheumatoid arthritis. Blood tests or X-rays are useful to check for these conditions.
Whatever the injury to the wrist, the chiropractor will tell you why it is happening and treat all the areas involved, so the wrist will heal in the quickest possible time.
