I had several people look at chunkys back over the years. They told me he was tight at times and the work they had done would release it. No further visits necessary. Ive questioned a funny area on his back where there is no hair. People just suggested perhaps its an old wound from when he was young. Im convinced now it's due to the spine underneath. No one ever said to me that there was possibly something going on in there when his back was checked. So I'm afraid now it's caused me not to have any faith in these physio etc. Knowing what I know now about his back and the symptoms ive read that other peoples horses have experienced before being diagnosed with KS I suspect he has been in pain for many years. He never complained and never did anything dangerous to indicate a severe problem but I realise now there have been hints for years.
