Experience with Xxterra
That would be purulent discharge aka pus :D Pus doesn't always mean infection; it can mean just immune response. It is composed of dead white blood cells that were involved in attacking the sarcoid tissue. I always saw it before sarcoid tissue sloughed off.
So it's a good thing in short? It means it's working? :?:
It means that the body is having an immune response, which generally is a good thing in this situation.
What do you know about the fluorouracil injections? Any experience with them? We had to change vets (other vet went on maternity leave) and the new vet is recommending them to us.
I personally have not used it, but have heard of it being used with good effects. You just have to be extremely careful with 5-FU as it is chemotherapy and there is no safe minimum exposure for those (for you or anyone else handling Lacey). It is another one of those multitude of treatments that work for some horses some of the time, which is the unfortunate finding of all the sarcoid treatments. Ask your vet if they have ever tried EqStim as another treatment option.
