i was told he has stomach ulcers and the vet said i need this...Homeoanimal brand,,really there nothing just as good to use here

Hi my horse has front and hind ulcers and i am currently treating them but I was wondering if it is ok to ride and lunge still.

Hi, we got a pony about 6 weeks ago and had her vet checked and everything was good. A few weeks ago she started becoming skiddish and her lower part of her belly is sensitive to the touch, while brushing, and sometime putting on her girth. She know bites doing these things when before she did not. I started to think maybe a ulcer? Our trainer said to buy over the counter Omeprazole rather than spending so much with Gastroguard. Will these work? I was also starting her on a daily probiotic. Can i due damage by treating her for an ulcer if she didnt have one, since I never had her scoped to be 100% sure.
