From february this year I am suffering from something that I can't figure out what it is. At first I was awakened with heavy breathing even I couldn't breathe until I took deep breath. After that I was treated with antihistamines pills which resulted with heart beating, nausea,heart pain, muscles were shaking etc. The heart echo was good, abdominal echo good, ECG was good, the x-ray of the chest was also good, the blood was fine (except that I have a little high bilirubin which they associate with gilbert syndrome. After all this I visited pulmologist which gave me fluticasone propionate, it got better but I still have chest pain and heaviness, stabbing pain in the heart, foggy brain sometimes, anxiety also. Today I had same symptoms, the blood pressure was fine but pulse 90. I can't figure what is my problem, so please I am asking what test should I run? What can be done which was not till now? Thank you in advance.
