Se sentir anxieux

I’m health anxiety sufferer and earlier today I had a pain in my leg, which I thought was a blood clot but went away, then my shoulder started to hurt which also went away, but now I feel nauseous and I have no idea what’s going on. My biggest fear is hea** failure. I can’t write out the full word. Is this normal? I hate this health anxiety that I developed last summer, I never used to be like this. I’m also going to the gym tomorrow because I really want to start going again but I’m scared about that too.

I get these symptoms too, I’ve made multiply doctor appointment and blood test, ecgs! They all come back positive?
my pain symtoms are stabbing pain (chest pain) shortness of breath and high heart rate even when doing nothing? I constantly worry about having a heart attack or something really bad happening, I can’t seem to take my mind of it. my doctor haven’t gave or diagnosed with anything but they think it could anxiety
I honestly wouldn’t worry about it. make a appointment and get doctors approval

yep, I’ve been to plenty of doctors. Did an ECG, chest x ray, and blood tests.. all normal.
