... severe pain in right shoulder blade, radiates thru to my chest (pressure is unbearable when I bend over). Three days later my arm started to get very painful, especially from armpit to elbow. Then went numb, tingling down thru my pinky and ring finger. Had a nerve test (negative), had an mri of spine, neck and brain, all normal. Told my doctor I suspect pancoast tumor since I have all symptoms (except drooping). He had an xray done, says there is no evidence of tumor. I have heard they are quite tricky and hard to see. Anyone think it could be something else? I am at wit's end here. Still in pain, arm still numb and chest hurts desperately. Thanks!
