Gosh, I cannot even imagine how frustrating it is not to have a definitive answer. That is so unfair! It seems like every time we *think* we know what you have, something changes everything.
All it takes is for a doc to look at you to see that there is something physically wrong with you. Doctors like to fix people, so it's probably just as frustrating for them not to be able to tell you what's causing your problems.
Just take it a day at a time, and know that things will get better again!
