I believe I have balanitis as I have a very sore tip of my penis plus I have a small but sore rash on the edge of my fore skin and a white cheese like discharge under the foreskin

I am 61 years old and there is no question of me having a sexually transmitted disease.

I have been unable to see a doctor as yet so have tried to treat the problem with an iodine based antiseptic cream but this has not helped. I have access to some Sudacrem but have not applied it.

I aim to see a doctor after the weekend but would it be a good idea to try the Sudacrem until I can get treatment from a doctor?
