I have been having some pretty funny symptoms as of late and was wondering if anyone could relate. Right under my left arm, on the side of my chest, I have what feels like buzzing. Its not in my arm but in my chest, between my armpit and nipple, on the outside of my chest. It comes and goes and brings no pain. It's almost like a very mild muscle spasm. My heartbeat seems very normal when this is happening but then I notice it, get scared, and my heartbeast accelerates. Its such a double edge sword because I can't figure out if the buzzing is directly related to my heart, or if I'm scaring myself. It just seems so close to my heart for it not to be heart related but then again, I don't know what else sits right there. It feels so weird and has been going on nonstop now for a few days. I feel fine otherwise, just super stressed because I can constantly feel the buzzing. Thanks for your help.
