Hello,Im not an expert but someone with past  heart isues,I was having for about the last year alot of problems,bloop pressure going up and down,pulse going high then dropping a little,I just came back yesterday form Heart Dr.after having stress test the other week,to find out I have 2 cloged arteries,so on monday i go for double Heart Cath,Please from someone that's been there get your dr.to check things.I also have a low thyroid,and i was having alot of severe fatique which i couldnt figure out the cause I guess I did now.This is all after spendind at least over 1 Year telling my Dr.at my local VA Hosp.of different problems and he ignored everything,so i was forced to go to a Heart Dr.outside the VA system.Jim
