These could be folliculitis
or could be insect bite induced lesions.
Do warm water compresses over the area and apply a topical antibiotic
cream like mupirocin or fusidic acid
acid atleat twice in a day Do not apply undiliuted dettol over affected area. To relieve pain and itch take an oral antihistamine and analgesic like cetirizine
and brufen. The lesions should resolve in few days.
Hope that helped.
