I have had a fungal infection on my penis and there was little trush under the foreskin and was suggested to use terbinaforce ointment and been using it for past 20 days and it went off. I haven't been using the cream for the past couple days and today I noticed a small red patch on the tip of the head of the penis and was also unable to pull the foreskin back as its paining a little, never had the pain while pulling the foreskin back earlier and it's the first time. Wanted to know what it is and am attaching images for further clarity.
