Talks about my Bubby Girl Katara

EDIT / Katara is on Digestive EQ
I didnt get to ride katara yesterday , as I brushed her she flinched as I brushed across her ribs , swishing the tail & pinned ears , repeated the brushing and she repeated her action! so I did the ‘ check ‘ and yep she reacted to each spot to indicate she has an ulcer!
I think a few stresses have got to her / my surgery I didnt see my horses for a few weeks , plus she doesn’t like when little Teddy isn’t in the same paddock!
So I Am treating her with Digestive EQ / Will get vet out of no improvement
I am a bit conflicted as I did come accross a fellow on , who shows that an ulcer can be mistaken for the diaphragm being out/ Jamed as if horse had ran into something solid , not to confuse myself I did look into this / time will tell of no improvement this is what I will seek attention on!
