I consulted another Urologist and he saw it again and said that it was normal infection. He suggested be Augmentin and
ITRACONAZOLE capsules. and also advised to apply Betadine on the head of the penis and the foreskin.
I followed that, the blisters have gone now, but I have red rashes (not wrinkles but lines and dotes) on the head of the penis. They seem to be more visible when the penis is erect. Also, if I apply betadine for 2-3 days, skin of the head becomes dry and gets wrinkles.
