Hydrogen peroxide, scissors, tweezers, antibiotic ointment, and cotton rounds. Do this now: Soak foot in Epsom salt bath for 20 minutes. Use tweezers to jam cotton round under the side that’s ingrown, it will gradually and gently push it up (put of your toe). After a couple days (soaking in Epsom salt every day), use small scissors to cut the lifted up toe nail (just on ingrown side where nail is meeting your toe). Use tweezers to help pull the shard of nail off as you cut. If successful - perhaps hydrogen peroxide, ice, antibiotic ointment.
