He was suffering from EXTREME stifle/flank area pain. You put the slightest touch in the area and he kicked out. Which for Drifter was a red flag for me immediately because he is pretty much non reactive. He also came up lame the other day, which the vet is saying he believes was caused by a strain due to Drifter trying to evade the massive pain he was feeling coupled with his tender back feet.
The difference in him once he was cleaned was AMAZING. I am talking completely different horse. I can rub all over him, brush him, push hard in the spots he was angry about before and he just relaxes into my touch like he used to. So the pain went away just about immediately.
He is getting his back shoes on tomorrow, so hopefully with his shoes, a clean sheath and a few days of small paddock rest he will be back to normal. I need to give his strain some time to heal but vet is confident it will not take longer than a week. There is a little swelling still on one side, though no heat. I am treating it with DSMO cream and hosing with cold water for 15 minutes every day 2x a day.
He is in a small paddock with another herd buddy who is also recuperating from some issues so they are keeping each other company. Hopefully he will be sound and ready to go by this time next week :)
