Hi. I was diagnosed with vasculitis a month ago (after many years) and I've just received a letter from the skin biopsy saying it is polyarteritis nodosa. The condition only affects my skin and peripheral nerves (at the moment). I'm Anca negative and bloods generally look normal. Can anyone advise how they know it is therefore PAN? Does PAN look different from an idiopathic vasculitis when seen in a biopsy?
Also has anyone else had vasculitis limited to skin and nerves - and at what stage should I expect sensory improvements? I regularly have numbness and buzzing in hands and feet still. I've just completed my third session of cyclophosphomide and am on 25mg pred (and reducing).
Any shared experiences appreciated!
