Lots of symptoms no answers...yet

Izzy has been in heat since the day I got her so about 7 weeks or so. I thought at first that is was just because of the move and the new horses, but I was told that she was often in heat prior to me adopting her. I have noticed that brushing or touching her belly was a problem, even things like reaching to grab blanket straps was like playing Russian roulette, you never know when your going to get kicked. This has gotten progressively worse. Even ground work has gotten worse, if I have to ask her "mid-section" to move away, especially on the left side she will kick out. She succeeded the other day. Most of this behavior I have took note and moved on.

A couple of days ago Izzy attacked Chevy. It was not like mares fighting for an alpha position, this looked like some stallions fighting. It stated off with Chevy, Izzy and Jasmine where turned out. They all get along and this is not something new. For the first the 5 minutes they all did there own thing and got along great. Then Chevy was rearing a little but it was very playful. Jasmine and Chevy were grooming each other on the withers while Izzy just sorta stood there watching. A few minutes later Izzy chased Chevy into the corner and kicked Chevy in the chest as hard as she could. Then she got low to the ground like a herding dog and chased Chevy in circles. With her ears back and her mouth open. It was not something that I have ever seen. There was a lot of biting and kicking before we could separate them.

Now Izzy's jolly ball that hangs in the stall is causing problems, she used to not mind it bumping into her or she played with it. But now if it touches her butt or side she kicks out. Something is causing her pain. She is not an aggressive horse, she is sweet. I am having the vet come out on the 27 th to do some tests and palpate her to check for cysts or tumors on her ovaries. Even though that would be a bad diagnoses it would explain what is going on and could be treated.
