LOL Dahlek---I am always wondering if that pin is clean!!
I would bet the farm, that if they did skin biopsies on people with autoimmune diseases, the whole gamut, from RA, Sjogrens, Lupus, Post Lyme, Sarcoidosis, Psoriasis and even the seronegative spondyloarthropathies, they would find some degree of PN. How many people with Fibro have had the skin biopsies?
Docs seem content to find one thing and say, 'There ya go, we got something", even if it isn't perfect.
I also have an issue with suppressing the immune system in diseases that have a known propensity to develop into Lymphoma. How can you win? I hope I can stick with my IVIG.
It seems the more I read on autoimmune disease, the more blurred the boundaries get, unless, you have a clear serological marker....and even then, those change!! Like I said before....Phooey on all this illness. I wish it would all go away.
