So this has been happening on and off for the past couple years, some days are decent, others are pretty miserable but theres no real trigger involved with whats happening to me.

Basically it feels like my pectoral muscle gets super tight/tense and then spasms causing this weird feeling in the left side of my chest, which is followed by radiating pain to my left shoulder and my left jaw. I've had heart tests done and everything came back normally too. Does anyone else get this?
