Im afraid i would stop riding her for the week. You could be making the situation worse if she has ulcers. It could also be dangerous with her bucking.
Im not sure changing the tack right now is a good idea. If you change lots of things you are never going to get to the bottom of the issue. Change one thing at a time.
You are changing the diet. Now offering meds. Thats enough for a month. Get her vet checked and sound internally before worrying about tack changes. First port of call my vet would be wanting to come out and see my horse if ulcers was suspected.
