There isn't often much discussion about physio. In the past I was offered a short 3 session course which gave me exercises but not much else. Since I've been off meds and feeling pretty bad, I decided to try more physio because I was threatened with an op for my knees and wanted to build up the muscle strength around them.
Had my second session with a (private) physio and it was well worth while.
She checked on the impact of the earlier exercises which I've been doing conscientiously, and gave me a very gentle massage on my knees to get the patella a bit more mobile. Now I can bend my knees more and they do feel freer. I've got to continue the exercises and also an additional one for my shoulder which is a bit tired after helping me to get up from seated.
People do talk about how exercise is good for both RA and OA and this bears it out I think. If you can, its well worth it I think.
