I was wondering if someone could help me a little bit , so basically about a month ago I started really listening to my heart after one night where I couldn't sleep because I could hear it in my ears. I thought there might have been something wrong with me , I then had a full blown panic attack where I thought I was having a heart attack so I was taken to er. They checked my oxygen levels and blood pressure but they couldn't get a good blood pressure reading as I was panicking every time they tried. I then had the same thing at night. I went the doctors and they did a blood test and a ecg but everything was normal , I was given diazepam but I don't like it so I don't take it. It's been over a month and some days are better than others but I get lots of pains in my arms and legs and back and also chest , mostly sharp pains at random or when I exhale hard. Also I can feel every little sensation in my body and also get muscle twitches that are visible but only really last a few seconds .This is just really unlike me because I used to exercise so much and now I just can't because I panic every time my heart rate increases , I can feel it every time because my throat and chest tighten.
