There is NO NEED to soak this pig's foot in Epsom salts. That is used to draw the swelling out of tissues, and this pig does not have any swelling.
@scootie, please stop giving medical advice -- not only will that treatment not help in this case, but pigs can be harmed by Epsom salts.
@
shweta.rawat, there is no need for treatment for your pig. Even if you took him to the vet and the bone were broken, they would probably do nothing to it because it will heal on its own, and there is no good way to splint a guinea pig's foot. Trying useless treatments is not going to help his foot heal.
