I can only remember with total horror that dreadful weekend when, despite every treatment (frog supports, bute, acp, diet, deep bed, no movement) my horse got worse and worse and the vet treating him wasnt on duty. I asked for iv painkillers and sedation to try and get him through until the Monday - and tbf he was improved by then but the damage was done (sinking and more rotation). He did have a short period of relative happiness out in the field some months later but I knew then that if I had known on day 1 what was to come (it was my first experience of this dreadful disease) I would have pts staight away. I know some cases do recover but, years later, the memory haunts me and fills me with pain. Im sorry if this isnt helpful but your awful situation has bought back that terrible time with a horse I bred and loved totally and watched go through real suffering because the vet and farrier wanted to see if they could save him.
