Without examination,confirmation of a diagnosis is tough,but it sounds like folliculitis or boils. Folliculitis is the inflammation of one or more hair follicles
. In most cases of folliculitis, the damaged follicles are then infected with the bacteria Staphylococcus (staph).
Pls keep the area clean and apply some topical antiseptics. Also wear loose-fitting cotton clothing and use an antibacterial soap or mild soap like dove.Avoid any kind of cosmetics. Topical antibiotics such as mupirocin or neomycin containing ointment are also useful.In case the symptoms persist then oral antibiotics may be needed.Pls consult a dermatologist in that case.
Hope it helps.Take care and pls do keep me posted if you have any additional queries.Kind regards.
