Could it be an abcess?
On Friday, my mom was riding my gelding and about 30 minutes into the ride, he started to limp. She got off, we untacked and waited for him to cool off. Then we felt his legs and hoof and nothing was wrong. We picked out his feet (she was riding in the sand arena- nothing was in his feet) and trotted him, but he was clearly limping (not like "I broke my leg" limping, but like his foot hurt). We soaked his foot in epsom salt and betadyne and put him in his stall.
The next day, we came, and trotted him. He trotted sound, hoof was normal temperature, so she got on and rode him. Again, about 40 minutes into the ride, he starts limping. We did the same thing as the day before and put him in his field. We though- if it's an abcess, he should walk on it anyways, and the ground was soft.
So Sunday comes, and we see him galloping around his field with his buddy. We think- he must be fine. Wrong. His right front foot was so hot. Like body temperature hot, while the other was cold (it was 30 degrees out). We trotted him and he was limping a little, but not much. We soaked it and put him in his stall. There was no other heat in his leg and no swelling.
Monday, Tuesday and today he has had a hot hoof and trotted lame, but walked fine. We keep soaking it. He still goes out in his field everyday and stall every night.
He had a twisted shoe about the middle of January where he was walking on the clip until he got brought in from the field that night. Could that have caused an abcess? It seems really long ago. He also got his feet done 2 weeks ago- could a nail be bothering him? A girl who does stalls at our barn is a farrier and she said that he would be more lame if it was an abcess. She would help us out a little bit more if she wasn't 7 months pregnant... Now it's like he's off, but not limping too bad. What could it be?
He has a history of mysterious lamenesses, but those were just out of the blue. He would start acting like his leg was broken in the middle or end of the ride, almost not being able to walk, but no heat or swelling. The lameness would be gone a few days later. He was diagnosed with Lymes in the fall and these types of lamenesses are symptoms. This isn't really the same as those times though. Should we remove the shoe or call the vet? Also, the working student seems to think he's faking, but I honestly don't think he's that smart, and his hoof is hot. Sorry for writing a book.
