my horse was scoped yesterday (been behaving quite badly but picture of health to look at and always eats well) sadly extensive ulcers found. but more worrying vet found strange nodule type lumps all over roof of stomach. quite linear in pattern. he's taken biopsy. thinks it could be general thickening from previous ulcer damage although site is unusual as do high. i should get results later in week but does anyone has any ideas/experience of similar?
