Jaydee Thanks for the info vet was back out and we have stopped the iceing. Vet decided the iceing wasnt really helping now. She gave him some stuff to help open up the bloodvessels don't recall what it is. He's still not out of the woods yet on this still has alot of heat in those hoofs. Problem is we don't know whats causing this so until blood work comes back its all a guess.Hes a grade 3 maybe closer to a 4 so its not good at all.Right now he's back down and has been for a while maybe only stands up for an hour at a time. Vet is doing all she can and going above and beyond for my horse she hasnt charged me a farm call for the last 3 visits. I know she coming from a distance too. Will be back again today to check on him. Iv been reseaching this on and off all night so I know what iam dealing with.
Lying down at this stage isnt a bad thing as its removing his weight from the downward pressure already forcing the pedal/coffin bone down. Just be sure he has hay and water he can reach, maybe soak some of the complete feed pellets that are mollasses free and specifically aimed at horses with IRS problems as he needs to eat to keep his metabolism healthy
Keeping his legs warm helps circulation - the Back on Track wraps that are held on with velcro are really good but polo wraps with a liner will do if you are OK with bandaging - not too tight though - just enough that they don't fall down.
You can pad his feet to help support the sole/frog and cushion them, diaper pads or foam (check out styrofoam) cut to size held on with vetwrap or tape, this will make weight bearing easier for him. Make sure his hooves are really clean and you change the padding regularly as the downside of wrapping is that you create a lovely breeding ground for bacterial and fungal infections but the benefit outweighs the risk which you can manage
The last post was also really good advice - far better for him to start his walking around in a soft indoor where its also warm
Please don't expect recovery to happen quickly and get disheartened when it doesnt because this is a long haul thing
Hope the blood tests are optimistic
