Me too! Knees are the main offenders as were hocks for my old chap! I have had a break of a couple of years but now planning to find myself another horse!
Keep going, painkillers, bute and wine (not sure who gets what!)
I had noticeable success using a joint supplement for our older gelding. I noticed they did a human version and it definitely makes a difference - as in I notice when I've forgotten to take it!
