Hi,
Welcome to health care magic,
It could be
balanitis or some allergic rashes over the penis but must be confirmed by clinical examiantion.
It would be also helpful for me to diagnose and rule out and if i would inspect the lesion by own eye.
The important thing is to diagnose it first by a clinical examination by a
general surgeon or a
dermatologist by doing inspection and palpation.
The following treatment would be helpful.
1) Hot Sitz 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 infection should start subsiding after 3 to 4 of Ointment application.
3. You can be given
oral antibiotics like cephalosporins (cefadroxyl or cefixime) or quinolones or macrolides but only after complete clinical examination.
Hope this information will be helpful to you.
Regards,
