Hello dr. My 5 year old kid fell on concrete surface and bruised on both the knees.. we visited dr he cleaned the wound and put bandage on it with ointment. After one day he removed the bandage and again cleaned it and put ointment. Today after cleaning I put soframycin ointment but still he keeps complaining abt pain and not able to bend knees.. as prescribed we are hi in ibulgesic 2 times a day from 2 days. Do we need to give TT injection as dr said no need and ho kuch time required to heal the wound completely.
