Well, vet has been - it wasn't quite as bad as we initially thought. On flexion she was nowhere near as stiff as he'd anticipated. Checking back in her notes he saw that it was particularly the right one that was worst so looks like it's progressed somewhat but we're going to try injections into the hocks next week. We've decided not to try Cartrophen again as I wasn't convinced that it did make a dramatic difference. Bute was discussed as an option but we are going to see what next week's treatment brings. The overall cost is not quite as bad as I'd worried about - probably looking at about £250 all in, so it's worth it to get her back to being comfortable in walk when ridden. We discussed what I wanted to do with her work wise, and as I only want very light schooling we are quite hopeful that this will yield some results. He did say that it would come and go (as I mentioned that only a few days ago she was seemingly improving). We also discussed a different supplement. So much information - think I'm going to write it all down before I forget!!!
