We're not medical professionals, so nobody here can really say what's going on. As a long-time anxiety sufferer, I would say this sounds pretty extreme to be caused by anxiety. A question I would ask is, before this event did something happen that might have triggered a massive anxiety reaction? Were you thinking severely anxious thoughts, and they would have to be pretty crippling thoughts, very intense, to cause such a reaction, when this happened? Anxiety is a thinking disease, though the cause isn't really known. If you don't think anxious thoughts, you aren't anxious. It often seems to start out of nowhere when you do start to get panic attacks, but you say you weren't having panic attacks before this started, but when you trace things back you generally do find you had them before, if less intensely and on a more episodic basis. In short, anxiety always goes along with anxious thoughts, and to have such an extreme physiological reaction the anxious thoughts would have to be very very powerful. And you say that didn't happen, which would lead me to say, find other docs for second opinions to make sure there's nothing physiological going on. I would also ask if you started taking any new medications before this happened, such as a bout of steroids. Look for triggers for extreme anxiety, and if there are none, it's highly possible it's not anxiety. You can be an anxious person and still get other problems not caused by it. Were you tested at least 3 time for covid?
Im sorry you ate going through this. I have acid reflux ehich causes at times shortness of breath, chest pains, lump in throat, mucous in throat, hoarseness, i also have a small hiatle hernia that sometimes pushes up causing these things. Anxiety makes everything worse. Right now i am going through high pulse scare. It was high at dr visit. Now its all i can think about which in turn makes it worse. Im trying meditations, comedy, and just keepung my mind occupied. For shortness of breath i was told that excersise or just running for awhile helps. Tell yourself this will not kill you. You are fine. It sounds like you were tested for alot of things. And they are normal. Maybe talk to dr again
They can give you somethong im sure. But try and take comfort in knowing you are not alone.
UPDATE (10/17): more testing has been done... I saw an ENT and they found nothing but a little redness in my throat. I'm going to have allergy testing next week and another spirometer test. I also had another chest x ray and a V/Q lung scan (which came back negative for pulmonary embolism). I had blood work which discovered I have a blood clotting gene mutation (which is not the cause of my current problems) and on Thursday I had CT scans with contrast of my chest, abdomen and pelvis which found nothing. That being said , I still feel super sick and am worried I have some rare or undiagnosed disease or something neurological cause the chest pain persists, the stomach pain persists, the shortness of breath persists - all of my symptoms persist despite the doctors saying that all I have is acid reflux, mild asthma, and anxiety.
