I am having sharp, stabbing pain in my shoulder (esp. my arm pit) that also sometimes appears in my upper arm, then goes to my lower arm (but, never both at the same time)... I m also having numbness on just my skin of the top of my lower arm (above the wrist/to the elbow). Also, my first 3 fingers are kinda numb, with a pins and needles feeling when I touch them. I ve seen a doctor, but he says it s a hairline fx. and I know this is wrong. Please, I just need some thoughts on this...
