Do not blindly believe what the doctors say. Check every box. I had similar symptoms and several docs wrote it off as being anxiety. Finally, I saw a good doctor who provided a full set of tests—beyond scans, basic bloodwork, etc. Seems that I was right… don’t be paranoid, but if you don’t feel right, make sure you’re exploring every possibility—from your lungs to your heart to every organ in your body. Wish I would have trusted my own instincts sooner and didn’t accept “anxiety” for an answer. Hoping whatever is going on with me is reversible. That said, one of the tests 100% confirmed that I’m in an emergency health situation and I’ve never been so scared in my entire life (lung function related — the last thing I expected — considering I’ve been feeling pressure in my head, internal quivers/tremors upon sleeping, and chest & stomach pains for so long, but those may have just been side symptoms of the bigger issue that was building around my lungs). Praying that I can recover and hope everyone reading this will take matters into their own hands and fight to get the medical care and consideration they deserve. Important to clarify: I haven’t been to Mayo Clinic before. I know they have a great reputation — The doctors that failed me are from other facilities.
