I had an appointment with a very helpful specialist Rheumatology nurse yesterday who pointed out that whilst I may feel well it's possible that the Vasculitis (GPA in my case) is still active and causing permanent damage to my blood vessels and implicated body parts. This was a little worrying because I'm only having blood tests to monitor the Vasculitis at 6 monthly intervals. I have monthly blood tests to monitor health which may be impacted by the 20mg of Methotrexate a week. I obviously need to follow this up because 6 months seems like a long time to wait if I don't have strong symptoms indicating a flare but the Vasculitis could be active and doing damage.
I thought it might be useful for everybody to be aware that just because you aren't aware of any symptoms, it's possible that the Vasculitis is still very active.
