I ve had two episodes of chest pain in the last couple of weeks that felt like heartburn/reflux but were not relieved by Hyoskyamine. Both times, the pain intensified and radiated into the jaw. Both times, baby asperin relieved the pain within 15 minutes. I have anxiety problems and use a very low dose of Xanax to sleep at night, but neither episode felt like a panic attack. Could this be angina? Can it wait until my regular physical in February? I am 68 and there is no history of heart problems in my family. Do not take BP or cholesterol medicine.
