What sorts of tests?
I'm a 21 year old female and I've been having dry eyes, dry mouth and swollen, hot, red, stiff, sore joints (both knees and fingers) which I'm not able to straighten when they become like this. I also have Raynaud's Disease, fatigue, nose ulcers, a few odd rashes. This started 7 months ago.
I've been seeing my GP who've run some blood tests (sed rate and ANA positive. CRP, CBC, RF, anti-CCP normal). I'm on a 1 month course of Prednisone and some stronger ibuprofen. The Prednisone is amazing! My doctor and the rheumatologist on call at the hospital said it's definitely some form of autoimmune inflammatory arthritis.
They've not been more specific than that, but I've done a bit of research and it seems like it's either going to be (sero-negative) Rheumatoid Arthritis, Lupus, Mixed Connective Tissue Disease or Sjogren's Syndrome.
I understand there are tests like lip biopsies and stuff that can be done to check for Sjogren's.
Can someone please elaborate on what's involved in these tests? A lip biopsy doesn't sound like fun..
