hello, I experienced a major chest pain a week ago after a craft show (carrying several items back to my car (I exhibit craft items) I just assumed I might have pulled something in lifting and carrying items, stabbing pains for about 10-15 minutes, also took Tums just in case of possible heartburn, It eased up and went away, since then it has come and gone again (no stabbing pains just a soreness in middle of chest) comes and goes, today chest is much tighter and hurting, wondering whether I should go to Dr and have it checked out. age 59, non smoker and non drinker, very healthy, slightly overweight, only take 5 mil a day for high blood pressure, occasional aleeve for back pain or sore muscles
