Okay, I just went through this myself
lol. I was trimming the mini's back hoof, with it held between my calves,
instead of up between my knees like on a bigger horse. I was
leaning way over, and he jerked his leg up and got me right in the tailbone with
the back of his hock. I suffered for a week or more before going to the
dr.
He told me to take large doses of Ibuprofen
(3 or 4) and then ice it for 15 minutes. I did this once or twice a day
for a few days, and it felt MUCH better!
