After experiencing chest pains, a somewhat accelerated heartbeat, a sore throat, and mucus, I visited my doctor and she gave me all the heart tests (EKG, d-dimer) and both were negative (so no heart problems here). She didn't really know what was wrong, but I later discovered that it could be a acid reflux problem. She recommended I take Zantac (75 mg).
After taking Zantac for a couple days, I find that my throat's still sore, I still have mucus (colorless), and my heart's beating heavy (I can feel the heart beating harder than normal, although the rate is around 60-80 bpm).
What's wrong with me?
