I'm 56 - 5'5" - weight 165 lbs. I've been having this achy pain just on the right side (nearest the center of my chest) for a couple of days. No other noticable symptoms although I have been under a lot of stress lately, i.e., husband had a massive HA in Feb., work stress, problems w/ my father-in-law's estate, economy. I am taking Wellbutrin for mild stress but I'm afraid this may be something related to my heart.
