Have had similar 237SJ - my advice is don't push it by using it in a position which causes pain, use ice and warmth alternatively and take Ibruprofen in a dose that works. I went down the physio, cortiszone blah, blah blah route and still ended up having an op. No trouble since, it's been fine. I strongly believe if it hurts don't use it and keep in mind, even if pain relief works, it may still be causing further damage to use the joint. Hope you feel better soon.
