I had chest pain across my chest that last 20 minutes moved to my left side chest ,then 2 days later woke up again in morning with pain on my left side Chest. I do have MS and take back often and neuron tin for the past 10 years. My BP is good and cholesterol OK. I am 47 years female, but my uncle died of heart attack at 47 and 2 other uncles needed stents.I did not want to go to ER because I thought it could be my MS. but I have to say I never felt this type pressure and squeezing in my chest quite like this before and did not feel like an MS symptom to me.I usually get spasms in feet or back or legs, more like a cramp , not squeezing like this. Each time it woke me up in morning out of a sleep. Could it be angina or my heart or MS? Could I wait until symptoms come back again to see a doctor?
