I'm a 41-year-old guy and I've been dealing with this chest pain on my left side along with some breathing issues for about 20 days now. I had an ECG and Stress Echo, and both came out normal. I'm really confused about what could be causing this pain since it's been going on for so long. Can you recommend any medications or maybe some other tests that might help figure out what's going on? I'd really appreciate any guidance you can offer.
