I am so sorry, as a fellow Brit all I can tell you is that the NHS at the moment is utterly broken and it's a fight to get any help at all. I'm very lucky I'm hugely serum positive but still find myself in a situation where I wrote begging to know what to do about serious side effects and don't even get my emails acknowledged, let alone answered. I'm currently in a 2 month pause of having no DMARD because I can't take HCQ and there's no appointment available to start me on MTX.

That doesn't help you, except maybe to know that you aren't alone?

There is a herb called Cats Claw that acts very much like methotrexate which you could perhaps try. I'm also taking MSM, liquorice root and curcumin (not turmeric, curcumin) all of which are proven and tested against inflammation and arthritis. Let me know of you want details of where to buy, they're all on Ebay but only some sources can be trusted.

I'm waiting on my latest set of, private, blood tests but I think I've managed to put myself in remission, given the huge improvements in my vasculitis and the absence of a single flare.

Good luck getting the treatment you need.
