@Andrew_P
How are you getting on now? Any progress re a diagnosis?
Your post stuck in my mind since I read it a while back - I think it was the Churgs Syndrome bit that registered with me as I'd never heard of it before.
Thanks for asking! Nothing conclusive, borderline ANCA test first one was lower. All other blood tests they did for autoimmune (10!) came back normal. My IgM is still high, which consultants view varies on from due to the swelling or like the last consultants view that my immune system is doing something/fighting as it is your bodies first line of defence. I think ultimately they will have to biopsy my Sinus, which I may arrange privately.
I think the joint pains and swelling on this post was due to the high dosages of Cortisone Steroids I was on, and tapering off too quickly.
Waiting on an appointment for St Johns institute which I have now but for the 3rd of April, which I cannot believe and I am going to try with my GP to get that improved. Cannot even circumvent it privately as apparently nowhere else like it in the UK. Been the worst year of my life since the swelling randomly started, made a lot worse by no one having a clue what is causing the symptoms and long waits in the NHS. The sensations in my facial\sinus area are unbelievable when its going mad and then it can be agony.
When I looked at both the things she focused on, my symptoms over the last 5 years have matched, so I can see her conclusion plus a birthmark type rash on my neck that I ignored for the last two years according to this lady is a Photosensitivity rash, also a sign of Autoimmune problems apparently.
I had never heard of any of this stuff before, and if I am honest always thought nothing much about autoimmune diseases being quite as serious. I still believe I have a sinus issue, but they don't!
