NSU stands for Non-Specific Urethritis and is a bacterial infection. Only men get this, and it’s an infection of the urethra (where your pee comes from).
How you get it:
- Many cases are thought to be caused by Chlamydia, but sometimes the cause is unknown.
- Often there are none, but there might be a discharge from the penis or a burning sensation when you pee.
If it’s not treated:
- NSU might be a sign of Chlamydia or Gonorrhoea, so the long term effects could be the same as for those.
