I have had chest pressure and pressure/pain in lower jaw/gums, ekg was normal, no shortness of breath, no sweating, no arm pain, take 81mg aspirin everyday at night because I am over 50 (58). I do not take any medications, BP 134/78, no diseases or conditions, parents are 80 and healthy, male sibling healthy. I do interval training (walk, jog, sprint) 3 miles, 4-5 days a week, lift weights same days. No fried foods, limited sugar. Doesn't get worse on exertion but just won't go away. Took 2 enteric coated aspirin 5 grains each about 6 hours ago, no relief.
