Carpal Tunnel Syndrome
The carpal tunnel is a passageway in the wrist. It can cause very bad hand and wrist symptoms. Passing through this tunnel is the median nerve and the tendons that connect the fingers to the muscles of the forearm. CTS occurs when this median nerve is pinched because of swelling of the nerve, tendons, or both. CTS can be caused by sports like racquetball or handball, daily activities like sewing, typing, writing, driving, painting, etc. It is common in people who perform repetitive motions of the hand and wrist. It is most common in women aged 30-50.
Symptoms:
Trigger Finger
Trigger finger is a condition in which your finger or thumb locks or catches in a bent position. The finger or thumb may straighten with a snap (like a trigger being pulled and released). In a severe case, the finger may lock in the bent position. This is caused by inflammation of the tendons in the finger. The tendon is covered by a protective sheath, which is lined with a lubricating fluid. When the tendon becomes inflamed, bending the finger or thumb may pull the inflamed portion through a narrowed tendon sheath, creating the snap or pop.
