My 3 yrs old daughter has a sore on her head, at first it looked like a ring worm i went to the chemist and they gave me vermox as well as the nystacid ointment. my problem is it now looks like a red bump with pus. please advise. ?

Some basics: Ringworm of the scalp is a deep infection within the hair roots.No topically applied cream/lotion will reach the depth required for a cure. It is not a worm but a fungus. Why anyone would use a worm medicine for this is confusing. These fungal infections can become secondarily infected by staph or strep. Cure may require a prescribed oral anti-fungal for a month along with an antibiotic.
