Hi,
Welcome to health care magic,
It could be balinitis or
balanoposthitis.
Can you please take a clinical photograph of that red spots or it must be examined by the doctor to get diagnosis confirmed.
The important thing is to diagnose it first by a clinical examination by a
general surgeon by doing inspection and palpation.
Here,it does not seem to be due to any chlamydia or any STDs as your partner was tested negative for herpes as stated by you.
The following treatment would be helpful.
1) Hot Seitz bath-Sit for 15-- 20 minutes and also clean off any clear or whitish secretion. Do it at least twice a day.
2. Local Steroid cream/ointment application- Clean off and wipe off the area clean and dry,following which apply local Steroid Ointment Like
Betamethasone The bump should start subsiding after 2-3 of Ointment application.
3. You can be given
oral antibiotics like cephalosporins (cefadroxyl or cefixime) or quinolones or macrolides.
Consult your general surgeon or
dermatologist for complete history and thoroughly clinical examination and further treatment.
Regards,
