I split my toe open and cracked the top of my toenail. i've been covering it and using peroxide and neosporin. will it heal in five days?

Toenail injury: Healing depends on the size and depth of the injury, but it often takes more than 5 days. If you develop fever, if the entire toe swells more and gets more red, or if you see increasing pus formation, a doctor needs to check this immediately. If it was a small superficial skin injury with localized redness that doesn't spread or get worse, it is okay to watch it for now.
