Anyone here get like chronic chest tightness… started for me in May and can last literally weeks/months… it’s my muscles, maybe intercoastal muscles it seems? Nothing showed up in cardiology work up, gastro work up including barium swallow or X-rays. Frankly the pain feels superficial/muscular and is all over my chest but especially center chest. I don’t have panic attacks often (last one was maybe October). I’m anxious over my chest being tight often. Worried it’s some kind of muscular disease or something.. anyone want to share their stories if they had something similar?
