Neuropathy.: Many types of neuropathy can produce symptoms like you describe. Some are viral and others can be produced by compression on a nerve. This is a problem that if it persists needs to be evaluated by a neurologist.

See an MD. : See a real MD to make sure there is nothing serious underlying your symptoms . Then, if nothing bad you an go to chiropractor for an expensive massage
