Hey ya’ll, just wanted to see if anyone else shares this experience. A tale as old as time in this sub, I went to the ER about two weeks ago after some chest tightness/pain. After all of the tests, I was told it’s costo.

I can usually feel a dull “pain” 24/7, mostly just an annoyance. However, yesterday I used a home chair back massager which felt great, however later last night I had the worst pain yet. It felt sharp and I felt it radiate across my whole chest, like burning. I’m thinking that this might have been brought on from overuse of both the backpod and the back massager I used.

Has anyone had intense flare ups from over stretching?
