Carpal Tunnel Syndrome
The carpal tunnel is a passageway in the wrist. 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:
- Pain in the hand and wrist
- Tingling and numbness
- Weakness
- Typically, patients will wake at night with a burning or aching
pain with numbness and tingling and will shake their hands to obtain
relief and restore sensation.
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.
Symptoms:
- Soreness at the base of the afflicted finger or thumb
- Painful clicking or snapping when attempting to flex or extend
- Catching worsens after inactivity
- In a more severe case, the finger may lock in either the extended
or flexed position and must be gently straightened with the opposite
hand
