I bought my QH a year ago and last winter he had been stiff on and off. Last winter his back hawks were hot off and on. I had them exray'd and the vet said it could just be growing pains. In the spring he went to training, the trainer didn't think he was stiff. I rode him all summer with a new saddle - he didn't seem stiff. In October when the ground froze we took his shoes off for the winter. He went lame really bad so we had to put special rubber sole shoes on him. I left him alone for one month letting him heal. So when I started to ride him in mid Dec. his back seems really sore and he trots very uncomfortably under saddle. I put an english saddle on him and he did the same thing. His withers and back have hot spots off and on. Would the lameness in Oct/Nov cause his back pain? If yes, do I let him sit for another month? Also his back hawks are hot again off and on.
