Does anyone know any conditions similar to carpal tunnel?

Pinched Nerve: Carpal tunnel syndrome causes numbness and tingling in the thumb index middle and ring fingers. One can get similar type symptoms from conditions such as a pinching nerve in the neck and possibly a pinched nerve in the elbow something called cubital tunnel syndrome which typically causes numbness and tingling in the ring and little finger.

Similar mechanism...: That is, swelling of the tissues around tendons, also causes trigger fingers and dequervain's tenosynovitis. Carpal tunnel syndrome is caused by compression of a peripheral nerve (median) and other nerves in the extremities can be compressed at a variety of sites, causing, for example, radial tunnel syndrome (radial), cubital tunnel syndrome (ulnar), and post. Tibial (tarsal tunnel.).
