My neurologist has suggested that I have low grade cerebral vasculitis. The symptoms, (mainly MS type + migraines) build up over time and usually respond to a short course of Prenisolone. This time however the steroids have not really worked. Admittedly, the three things that make it worse have all come into play (stress, monthly cycle due and infection [UTI] at once). Blood tests have revealed a high WBC. Didn’t think this was likely while on steroids. Also I have just been to A and E as I developed a granuloma on my thumb which wouldn’t stop bleeding. Could this be related to a different vasculitis?
