I have had this 4 to 5 times since last April, visited the doctors about it 3 times. They just shrug it of saying trapped nerve or they don't know. It starts with a pain in my armpit always on the right, my arm then feels funny. Sort of numb. My right shoulder blade also aches a bit. This has been like this now since Monday. Today i feel as if i have a chest infection coming also. I also have had a bit of a cold since monday. This seems to have started happening since i quite smoking and normally only get it when i get cold. Anyone else have the same or similar?
