Thanks for posting your query at DoctorSpring.com
I can understand your concern.
From the pictures, it seems to be a case of scabies with a hypersensitive reaction to the mite antigen.
As a result of which you have those multiple lesions on the pubic area, thigh and penis.
I would recommend taking an anti histamine like claritin 10 mg once a day for a week.
Also application of cortisone lotion mixed with mupirocin cream twice a day on the affected areas for a week.
Repeat application of permethrin cream ten days after the first application will be advisable.
Please let me know if you have any queries.
