I had been having pins and needles in my chest, arms and back on and off for about 4 days. Therefore I went to my local GP, he checked my pulse which was 115 ((after I got home it had gone down to about 80)) my oxygen and pressure was fine. I can lift both of my arms up totally fine, I can breathe fine. He told me that it was just my muscles playing up, I don't know If I should go back or have a second opinion or not. Can't help but worry.
