Hello sir, I have some warts on my penis since 10-12 yrs, I recently consulted with a dermatologist and he prescribed VDRL test (result-non reactive) and also Azithromycin, Acutret(Isotretinoin), Vitamin (D3), and Fusidic Acid cream however there are not mejor effevt in 15 days. Is it some bacterial infection or any viral infection? Please note that I never ever have any type of sexual activity or any exposure to drugs. I smoke regularly since last 3 years. Your suggestion matters as I do not have a very well qualified doctor here. Thank you and god bless you.
