I am an overweight 50+ y/o postmenopausal female without a personal cardiac history (but positive family history--mother MI at 60). Normal BP, elevated cholesterol/triglycerides (but improving), not diabetic. History of asymptomatic gallstones. Was sitting at my desk when had sudden pain noticed first in right ear/jaw. It radiated to mid-chest, right shoulder/back. Had something that felt like mid indigestion. Felt hot. I felt slightly lightheaded but may have been hyperventilating due to pain and anxiety. No nausea, vomiting. Pain was intense at first--8-9 on a 1-10 scale but the intensity was intermittent--nearly unbearable for a while, decreased a little, bad again, etc. The pain lasted for about 45 minutes, then completely resolved, leaving me totally exhausted. Have had no further symptoms other than fatigue and an occasional mild colicky pain which I associate with gall bladder. Even though some of the symptoms overlap with cardiac problems, my gut feeling is that this is my gall bladder. It's all been on the right side. And no, I did not see a MD when this occurred. Does this sound more consistent with cardiac or gall bladder pathology?
