Hello everyone? I know this probably seems like a stupid question, but I wanted to ask because I am just so uncertain with my symptoms. I have Prinzmetal's angina and all day yesterday I was having cardiac spams, not big ones, but sort of continuously. Then last night, I was having stronger ones and my left arm was weird feeling and tingly. I took some aspirins and went to bed. While laying in bed, I started feeling funny all over, sort of nauseous so I got up and got my nitro. I have not taken it yet at all, so am somewhat nervous (of the unknown). I decided to sit up in a chair we have in the living room. I was still having the other symptoms. I was so tired that at some point I fell asleep. My question is "When or if at all, should I have taken the nitro?" It did not get worse, I did sleep all night and just got up, but am wondering if it was a precursor to a heart attack or a really small one. Any advice would be welcome, thank you!
