@leetaanderson I had a Baker's cyst when younger too and had a torn piece of cartilage removed. Just before my pmr diagnosis I had a return Baker's cyst (same knee) and as the cyst was finally draining and getting better I had a really rapid attack of pmr- I absolutely do not know that the two are related but my physio said they do show the same inflammatory markers (but again- so do lots of things I think). Looking back, I think that I had had a couple of mild attacks of pmr earlier in life (I was diagnosed in my 50s for what it's worth) but went for rheumatoid arthritis tests due to this being a common family thing. At the end of the day I just keep trying to manage the pmr symptoms and not aggravate my knee too much. It's been 4 years on prednisone for me and in New Zealand pmr is treated by general practitioners on the whole, so I'm very interested to read what others have to say about the biological treatments etc. and what rheumatologists have to offer.
