heat in the hawk of my horse

My horse was out in the field on rest for a week and i started him bac slowly with short simple exercicing and then this morning i started small jumps with him. After 2 jumps he seamed off so i got off to make sure everything was ok with him. Then i get back on him and ride him for about 20 more minutes. when im done and rincing him off i found that i his left hind hawk had lots of heeat in it and he was walking kinda funny on it. I poutlices it adn wrapped it. Theres still lots of heat in it. What do i do ???

Your horse has pulled a ligament or tendon in his hock from over exertion. call your vet and stick to walking him gently to avoid causing more damage. Your vet will advise you on treating this but remember these injuries can happen very easily when an soft horse is coming back into work. :)
