I am 45, smoke 4-5 cigarettes a day, and am on meds for GERD, prostate issues, sleep muscle tension and allergies. I was driving home last night in crawling traffic and getting tense to say the least. I experienced a moderate to severe pain in my chest that radiated to my jaw. This happened once before, several months ago, and I attributed to taking supplemenst on an empty stomach. My last BP was 130/72, just last week. I have had neck and headaches for about three weeks, thus the muscle relaxers from my MD. Is there any profit in seing a doctor now that the episode has passed..it lasted about 1/2 hour.
