Bit of background, I did some exercise on Tuesday that I haven't done for a while. This all started on Wednesday. I'm now exhausted by even just going up the stairs, getting lower chest tightening / spasms on taking deep breaths, moving around, particularly bending forwards. I keep going dizzy and lightheaded with a pressure feeling in my head and getting more palpitations than usual. I bent down to pick something up earlier that was only a tiny bit heavy and saw stars and thought I was going to pass out. I am really stressed because of the chest pain but gp has just given me omeprazole again to help with the reflux, which I know I do have because I have a hiatus hernia but it's never been this bad before. It usually just a dull ache across my diaphragm rather than a spasm. When it spasms I can feel it across most of my chest/breast area. When I get a spasm it's almost like my heart beat also makes it hurt for a few seconds, if that makes sense. I'm really scared I have something up with my heart and because I have reflux issues the gp is just assuming it's that. But I do also have anxiety, which could be making all of this worse. Can anyone relate? I feel like I'm not being taken seriously by the gp because of my anxiety and reflux history :(
