I went a few days between fly spray and she welts on her like yours dose from insect bites.....so that is what I assumed. But her edema didn't stick around long like your horse's did...
Tiny, no! She really is enjoying it. She'll hold a back leg up to "help us" get under (or prove her point like "under here!!")... Picture the look on someones face when my mare backs up and rolls her hip as such :)
Yes when horses go to scratch their tail heads from being itchy, listerine helps to ward off the itchy feeling. I'm not sure if aloe would work the same, or tea tree oil. Just what came to mind if this was my horse what I would try.
My TB, Eclipse, tried to jump over our fence one time and hit his chest and had something similar to this on his chest. We took him to the vet because he also scratched his legs and chest, and the vet told us it would go away and it did. He was also on a IV antibiotic, but I'm not sure if that played a part in it going away in a week or so. I hoped this helped:)
We have had a few allergic reactions over our 35+ years, but none that looked like that. My vet told us to use Benadryl gel, lotion or cream. If it is an allergic reaction it will help, if its not it won't hurt. The vet also has something a bit stronger, sorry I don't remember what it was, but I'll try to find out. Some linament might help if its edema, it improves the circulation to the area and will help move the fluid out.
Nope. Its been here for some time, I don't think that its just going to go away.
She does have bug bites, the bugs are aweful this year. That comes and goes but this has been here since before the bugs were bad. I really wonder if its just extra skin? She is a lot smaller than she used to be but that's happened over a matter of years. This I just noticed at some point this spring.
You can see it from a distance, like in this photo from last week...
New Image - a few of our mares came down with the same thing. Vet said it was bug bites with resulting histamine reaction/fluid build up in the area. Some of the early hay also contains weeds which some horses react to and causes weird edema. Some Swat, really good bug spray, and baby oil/ MTG to the belly and it was gone in a few days. Anahist can help too.
The bumps look like the hives one of our geldings had, but his were much more spread out.
Could she have laid in something that cause an allergic reaction, like the way people get poison ivy/oak/sumac/etc?
I don't even know if they can get reactions that way O.o
I hope she gets better(:
