Hi, Welcome to Healthcare Magic Forum.
First clean it with cold water to control pain, apply T-Bact ointment along with Topical antibiotic
ointment as and when you need until the wound heals and cover it with a sterile gauze. If the pain persists give him Ibugesic
Plus Syrup 2tsp thrice daily for 3 days. It will prevent fever and take care of pain. If the blister
forms, do not burst it, let it burst on itself.
