Sharp sudden pain under arm - is this from stress?
I sometimes have a sharp pain under my arm - it feels like someone pokes me with a long sharp needle inside of my arm just above my right armpit. It comes really fast and goes away just as fast. It almost makes me jump and then when I touch the area, there's no pain at all. It's very weird and almost seems like my mind in creating the pain or some type of neurological problem. It doesn't happen all the time but it can happen at any time and sometimes there can be a couple of times within a few minutes of each other. Since I don't feel any pain after it happens when I touch it, it doesn't seem like I need a physical check. I was wondering if anyone else experiences this same problem, if it's just stress, or if it's serious and I should get it checked out?
