imy left arm from my shoulder to my fingers has been tingling for about 4 days now, it feels really heavy and the sensation is gradually getting worse. i've had it before but the doctor didn't say much.
Sounds like a trapped nerve to me. I have had one in my neck but my husband is going for an op in Oct for one in his elbow. He has had all the tests and an op is the best thing in his case. Go see a different doc.
