How long does it take for a stone bruise to heal?  Thought it was an abcess so treated my horse for a solid week but it never busted.  Took him to the vet and got his foot xrayed no abcess everything mechanically looks great but vet said stone bruise.  Its been a little over 3 weeks and I can just barely see a gimp on harder ground.  Vet said light riding for the next couple weeks.  He said sometimes these things linger on.  I have never had one with a stone bruise.  

Did the vet find a sore spot with the hoof testers ?

DiO works really well on stone bruises, just apply to the sole. I've had them go away in half the time since I started using it on them. 

My shoer put a felt pad just underneath the shoe and she was good to go in 2 days. I too thought it was an ancess and after a week my vet said stone bruise. He said it could take awhile but my shoer said this would work and it did!

isoxuprine is great for bruises! 

I've also used the DiO gel on a horse's stone bruise this summer, within a few days I'd say it was gone.
