Thank you for your query at DoctorSpring.com
I understand your concern.
So from the history you have given, the most probable diagnosis seems to be fungal infection. I want to have a look at the pic of your glans.
Edit - The Doctor missed to review the pictures you have already shared. I the in-house physician has intimated the Doctor for the same, you should be getting an updated reply very soon.
Please feel free to discuss further,
Dr. Rajiv Goel

I'm still waiting for the updated reply.
It is possible that you have fixed drug reaction. You have developed this in response to intake of antibiotic rather than infection.
You should see your doctor and apply steroid cream under his care and you shall improve.
