What is a balanitis and what are the symptoms?

Balanitis is an inflammation of the end of the penis (the glans). Often the foreskin is also inflamed at the same time as the glans. (The foreskin is the loose skin that covers the glans if you have not been circumcised.) Balanitis is common, and it can occur at any age.
Symptoms include redness, irritation, and soreness of the end of the penis. It can range from a small patch of redness confined to part of the skin surface of the glans, to the whole glans becoming red, swollen and painful. Sometimes there is a thick clumpy discharge which comes from under the foreskin.
