As i write this mail, I am experiencing a flutter in my right upper arm. This is on since a few hours. I work out everyday. Recently I got the Tennis Elbow on the same hand and I am treating the same with ice pack and anti infamatory ointment. I am 42, of slim built, do not smoke, hardly drink. Mostly maintian a healthy lifestyle. Could you please explain this phenomenon? I have experienced mild such flutters at some nerve points, but none lasted beyond a few minutes. Many thanks in advance.
