Rolling with Autoimmune Inflammatory Arthritis (Psoriatic)

I am a 52 year old purple belt. I've had Psoriatic Arthritis in the past, but it has come back and likely to have to go onto DMARD's.

I'm interested in anyone else that has trained on DMARD's or Bioligics? I am 6 weeks from seeing a specialist. At the moment I can barely drill.

How bad when you started taking a DMARD and how long before you got back to rolling?
