To treat your skin lesion-
Do warm moist compresses
Apply topical antibiotic
cream like nadifloxacin
or fusidic acid
If its still swollen and painful you might require an oral painkiller and antiinflammatory like ibuprofen
If the lesion does not show signs of resolution you might require a course of antibiotics also.
Kindly consult a dermatologist
for prescription of these drugs.
Never manipulate any abscess/ boil/ pimple on face as it may have serious complications. All infected cystic nodular lesions should always be drained by a medical professional.
Hope that answers your query. Take care.
