Your symptoms resemble that of a
carpal tunnel syndrome; unable to hold,
pain, limited motion in the hand etc. Does your condition get worse in the nights? What was the cause for carpal tunnel syndrome previously?
The usual causes are pregnancy, hypothyroidism, arthritis, obesity, over use like continuous typing, diabetes, and trauma.
Some rare diseases can cause deposition of abnormal substances in and around the carpal tunnel, leading to nerve irritation.
