The autoimmune aspect and risk of flare is greater then with your PN....in my opinion. The autoimmune response can be triggered by anything from an injection, a simple cold, stress, surgery, injury, etc. It doesn't take much to set off the immune system and in your case, autoimmune process.

I can't imagine your rheumatologist or endocinologist would recommend such a procedure....but you should ask them before proceeding.
