@crypt0cu1t I almost envy your situation. You are seen by very knowledgeable experts who are interested in solving the puzzle, they odered these great tests for you, and you already have some findings that are admittedly associated with disease(s).
The road to treatment may be rough, as it takes so much time to have all these appointments and until everything is approved. Uncertainty is a huge part in chronic illness: Will I get the right treatment? Will it help? When? Will I get my life back?
But I honestly think that you are a lucky one and things will work out for you in the near future!
I hope your appointment on tuesday will bring more good info, and that the 3 experts will combine their knowledge. Maybe you'll not get a 'name tag' on your disease, maybe it is a combination of different diseases (autoimmune diseases seem to like company).
But I wouldn't be surprised if you'll write another success story like
@Gingergrrl !
Best wishes and a (metric) ton of patience!
