Wysteria... I'm so sorry you're dealing with this, it sounds incredibly painful and frustrating.
I don't have any hard evidence, but I know I tend to get physically sick or pain when things aren't going well for me.

Even simple things... like I'm stressed about big therapy things, so my sleep gets messed up, which means I had a killer headache all day today and spent most of the afternoon in bed with the blinds drawn trying to get my body to sort of "normalize". Not fun.
Is there really nothing your doctor can do to help? Saying, "it may go away on its own" doesn't seem helpful to me... Is there anyway to maybe get a consult with a different doctor? The whole things sounds so frustrating... I wish I had good advice for you!
