Possibly: This is one of those problems where a visit to your doctor is necessary to figure out what's going on. Only after a thorough evaluation, including examination and possibly labs and other tests, can your doctor correctly diagnose you and treat you effectively.

It is possible: Nerve compression is a possibility. There may be an entrapment or injury to the nerve. Have it evaluated by a professional to determine the diagnosis and to get the appropriate treatment.
