i have developed a unique problem in my right hand thumb. when i start writing suddenly my thumb revolves around my pen grip.i am unable to write even my own signature. i am not been in a postion to make grip for writing. i have consulted many doctors. i got EMG done as well as nurve conduction study. i also got cervical spine MRI. all reports are positive. still my problem remains un diagonised.
