Hi, Welcome to Health care magic forum.
As you describe, there appears to be some skin infection
, or some lice
of type which usually stay in pubic hair.
I advise you to consult a dermatologist
for diagnosis and treatment.
I usually prescribe to my patient with such symptoms grisofulvin pyrimethamimine ointment, and ketokonazole soap. As well cefixime
Wishing for a quick and complete recovery. Thank you.
