Please help me is this anxiety or something else?

Hi everyone, I have suffered for health anxiety for a good five years now. It is on and off but right now it is intense. For the past three weeks I have this feeling in my upper left arm like a prickly needle stick, it is in the same exact spot every time. It is scaring the daylights out of me. It also comes out of nowhere when I am not thinking about it... It started one night when my son fell asleep on me, I started to feel that same spot throb and I got worried, that night it throbbed on and off and the next day I was left with this feeling....has anyone experienced something similar?

I have not experienced this before though I have some strange feelings in my shoulder from some surgeries I had before. I think that the nerves were moved. I am suspecting it is a nerve with you too. maybe it was pressed upon. If it becomes bothersome I would talk to the doc. But right now it sounds annoying, but I wouldn't worry too much.

Have a nice day.

Hugs, Karen...
