I just need some advice, I can't tell if this is a long period of anxiety like a prolonged anxiety attack or something worse. I went to the ER last Monday (8/31) for a high heart rate and palpitations. I was definitely in an anxious state. Since then I've been all out of wack. Just walking up the stairs can get my legs really tired and send my heart rate up. I've been having random chest pain. Today I had bad anxiety to the point where my heart rate was constantly going up and down. I get a bit winded easily. Today I also noticed one of my legs is a bit swollen. I'm having some digestive problems too, but I know anxiety can cause that. I'm being referred to a cardiologist and following up with my normal doctor just in case but I'm wondering if anyone else has had things like this happen? I'm trying to not make it worse by being in a constant state of anxiety wondering if I have a heart problem. TIA.
