Hi its my first time posting on here. Im really sick of this HA. My latest worry is that im having a heart attack, im constantly burping then get chest and arm pain in the left side, its generally worse in the evening, I had a ECG a few weeks ago after i called an ambulance at 2am and that was normal and my GP also done loads of blood tests that came back normal, but I still constantly thinks they missed something. Im at a loss as how to cope anymore, I just want it to go away and get these awful thoughts out of my head
