I have the same thing. Everything comes back normal. I am on a low dose of propranolol (10 mg. twice a day) and it controls it for the most part. I can not have ANY caffeine, that is an automatic trigger for me. I do have Mitral Valve Prolapse but it’s not bad at all so they said the pain is not from that just from POTS. Do you have POTS?
I I don’t know yet if I have POTS. I think I probably do. I was told the chest pain is due to the joints along my rib cage. I don’t know if I believe it, because I continue to have pain and it is severe at times.
