Possible Wasp Sting-Treatment?
So this morning I went to get Frosty ready for our lesson, and was horrified to find that he'd pretty much rubbed his hair off a large patch of his neck (along with part of his mane...That's a pain.). It looked horrible and seemed to be wet- maybe with sweat, I'm not sure. I cleaned it off really well, and noticed that it was also hot in comparison to the rest of him. He also showed discomfort whenever I messed with it, though I think the cold water might of relieved some of that. Anyway, it wasn't until after I'd cleaned it that I noticed there was some swelling below and around the bare patch as well. My trainer, when he showed up, said it was probably a wasp sting or some sort of insect sting, and he'd been rubbing and itching at it. We didn't ride, since he didn't want it to become more inflamed.
He suggested any sort of ointment containing Cortisone, which we found and then put on all over the swollen and bare places. I'm going to go repeat that again later this afternoon, and then in the morning, and just keep an close watch on it. Also, he suggested Epsom salts in his water, and we'll do that as well.
What I'm wondering is if this is the only treatment, or if there is more that we could do. Also, would Benadryl be at all helpful in this situation? Thanks.
