My horse was diagnosed with cushings 5 weeks ago and is now on Pergolide and her ACTH levels are gradually coming under control. I last rode her almost 3 weeks ago, just a gentle wander with a little trot and the next day there was a pulse in one front foot and heat around the coronet band. On the vets advice (over the phone) I kept her in and gave her Bute, a week or so later there was little improvement on the heat although the pulse seems better. The vet came out to take blood for the cushings and I asked him to take a look. She is slightly lame (2/10) and he said it was ok for her to have restricted turn out so she has been going out for 2 hours a day for a week now. The heat is still there and obviously I am not riding her at the moment. I just wondered if anyone had any thoughts/advice - the vet thinks it may be cushings related and will come under control when the drug is at the correct level but I wondered if it may be something separate? The Pergolide was increased a week ago tomorrow and it just doesn't seem to be any better. I initially thought maybe early/mild laminitis but its not really progressed and obviously the the vet said it was ok for her to go out albeit only for a couple of hours. I just can't see how its going to get better if I we don't even know what is causing it and now I'm really worrying.
