How to soak an ingrown toenail
Prepare a warm foot bath.
The purpose of soaking your affected toe/foot in a warm bath is essentially two-fold: to reduce the discomfort and to soften the toenail in efforts to either trim it or put something under it to relieve the pressure. Grab a container that's big enough for your entire foot and fill it with very warm water.
Consider adding some epsom salt, as it can significantly reduce pain and swelling. The magnesium in the salt will also help the foot muscles relax.
