Not all men who have inflammation will show any signs or symptoms, or they may be so mild they are not noticed.
If signs and symptoms do occur they usually show up within 2–4 weeks of contact with an infection, but they can sometimes appear within a day or two (depending on the cause of the inflammation). If you do get signs and symptoms you might notice:
A white or cloudy discharge from the tip of the penis, usually more noticeable first thing in the morning.
Difficulty, pain or a burning sensation when passing urine.
The feeling that you need to pass urine frequently.
Itching or irritation at the end of the urethra.
Depending on the cause of the inflammation there may also be other symptoms that are specific to particular infections.
