I m a 42 year old female. My neck, shoulders and arms were hurting, squeezing, burning and very achy. Shortly after getting in the bath I was having a hard time catching my breath and my heart was pounding hard. I took my pulse and it was 103. It s been about 15 mins, my heart beat is at 90, the pain is all but gone but I feel very shaky. Should I go to the er?
