Some structures in the body, for example nerves and ligaments, go through tunnels. One such busy tunnel is the carpal tunnel, through which a nerve, ligaments and blood vessels travel through the wrist and to the fingers. A healthy carpal tunnel has ample room. But repetitive use of the hands and wrists, for example through typing, knitting, carpentry and handling cash registers, can cause tissue inflammation which then compresses the median nerve, resulting in weakness, pain when gripping, plus burning, aching or tingling. These sensations could radiate to the forearm and shoulder. What can those with carpal tunnel syndrome (CTS) do?
