symptoms of SI, kissing spines?

[ahlam1399]

Hey everyone,this is a long one, so bare with please...i?m at my wits end with my boy, he?s being so vague with his problems!!!! :( Basically he?s been lacking hind impulsion, worse on corners and circles (feels worse to me than he looks), doesn?t want to go forward in canter (or ends up complying but he?s stroppy about it), struggles to pick up right lead canter (runs in trot instead etc.)Had physio out, she watched him lunge, said he wasn?t right, i REALLY had to chase him on the lunge (don?t normally), she thought he was slightly short on LH. Had the vet out, he watched him lunge, and again he was REALLY lazy (unlike him). He thought he may have suspensory damage to LH as he did palpate a bit sore there. Flash forward to a week (he only went on the walker and was handgrazed). Vet out to scan & x-ray. Scan showed minimal wear and tear to suspensory but nothing that he could say is the actual problem. X-rays of hocks and fetlocks - hocks are good, slight changes on fetlocks but again nothin that he could say is the problem/would cause symptoms. He is 13 so there is expected changes etc. all horses would, just like people. He?s recommended sending him to Newmarket for a few days for lameness exams, nerve blocks etc. But i?m losing the plot because i?ve been riding him since the scans to see if he?s ?miraculously? recovered himself & he is a little better, still not right, but one of the staff also pointed out that he looks a tad short on his LH also, but she REALLY had to look. But anyway we?re not sure whether his little improvement is only related to the fact he?s had some time off, not done anything or been in the field and so he?s just happy, rather than the problem being gone etc. I would hate to send him to Newmarket spend ££££ waste their time, for them to not find anything - but obviously i want my horse happy and pain free!!!!I?m thinking perhaps it?s higher up? Sacroiliac, kissing spines maybe? What sort of symptoms are there for these? Wish he?d stop being so vague :( thanks
