Khan, there is way too little information here to allow helpful comment. There are many causes, symptoms, sites of involvement, etc. Please share to the extent you are comfortable doing so.
I remember an urban syndrome during my training (having nothing to do with Khan's problem) called Park Bench Palsy. Hard core alcoholics would fall asleep or unconscious on the park bench with their arm draped over the back of the bench and come in the next day with partially paralyzed arms from compression of the nerve.
But back to Khan, Martha's advice is probably sound.
