My gelding was trimed four days ago and has been lame/sore in both front feet since then. I was thinking that I would start treating his feet with Iodine to see if it was just his soles bothering him. Friend of mine suggested DMSO but I can't seem to find any info about using it on feet online. I have some and have used it for edemas before, but never on feet. Anybody have any experiance or suggestions? Four days is a long time to be sore after a trim IMO, and I would love to get him feeling better ASAP!
