I have a pins & needles feeling deep into my left armpit that radiates down the inside of my arm to my elbow, several times during the day. Occasionally while this is happening, i will also have burning pain in the same shoulder - rotator cuff area radiating down the outside of the arm to the elbow. When this happens suddenly and is intense it scares me into thinking I may be having a heart attack, but I don't have any other symptoms, no shortness of breath, no heavyness, no sweats, otherwise I am a healthy 51 year old female. I thought it could be a pinched nerve, but would it come on so suddenly, last for about 15 mins, then subside. This first happened 6 months ago and then again 2 weeks ago. I don't have any neck pain when this happens. Can you have a pinched nerve w/o neck pain?
