I hope you feel better soon, my entire life has had a few "we don't know what's wrong" and since I have an anxiety disorder, then it gets brushed off that I'm just a stressed out woman and need to "relax". One doc said my migraines were anxiety, next one that has his head out of his ass figured out what actual type of migraine it was and got me on a brand new drug that has made my life much better most days. Sometimes you gotta keep looking for someone that gives a shit!
I do know the mental component affects the physical, and makes it worse, but for the things that are physical and noted I hope no more surgeries and I can live with the pain I'm at now. Tired of being poked at, I am sure you get that too!
In other words, get better and I am sending vibes that they can find out what the problem is. But sometimes ya gotta live with some bullshit in life
