I am 27 years old. There is itching, redness and red spot in the head of my penis. I went to a dermatologist and he said that this is blantatis and prescribed one antifungal, antibacterial and anti inflammatory cream named funzi-mx made by company corona. When I applied this cream in the affectd area the problems get resolved in 3 -4 days and my penis become normal. But after I stopped using this cream then symtoms again appeared. So whenever I applied this cream problem gets resolved but ot comes again once I stop using it. I become irritated using it. Kindly suggest me what can I do ?
