Re: Tingling sensation in left arm and hand?

Tingling (paresthesias) in the arm usually is traceable to impingement of one of the upper thoracic nerves by either a disc or a vertebra or an arthritic process or even a tendon injury near the nerve root.
If it goes on long, often a chiropractor or some light traction can afford a quick cure.

I doubt it has anything to do with the myalgia or myositis of statin use which generally affects the large muscles (like thighs.)

If it's only in the lower arm, then it could be the beginning of a tennis elbow (no tennis required :D).
