NSU is a common condition which results in painful or frequent passing of urine. It can be sexually transmitted, but it can also be caused by your body’s own natural bacteria moving into the very tip of your urethra – the hole you pass urine through – and setting up an inflammation resulting in pain.
It is an inflammation of the urethra – the tube you pass urine through. It can occur through sexual activity with others where bacteria which live in their throats, rectums or vaginas may get into your urethra and cause inflammation. These can be quite innocent bacteria which end up in the wrong place. Equally, you can spread bacteria from hands into the urethra during masturbation.

Any sexual activity may result in you developing it. It is non-specific by definition so simple throat bugs may cause problems for example.
You may develop a slight discharge, especially if male. You are likely to notice discomfort when you pass urine and to want to pass urine more frequently.
Be vigilant and get yourself checked when you have unprotected sex with a new partner. If you’re having sex outside your usual relationship, make sure you protect your regular partner by getting tested before you have sex again.

Testing for NSU is straightforward and painless. A simple urine test and a painless genital swab are taken. Results are available within 48 hours.
Treatment is easy once detected, with a course of antibiotics which will cure the infection.



Wow! Dr. Dan was extremely knowledgeable and attentive to my health and well being. I’m so glad to have found him!
I have been going to Dr Wright for a number of years now. He is highly knowledgeable, compassionate, open minded and efficient, I couldn’t recommend him highly enough
I have been a patient of Doctor Dan for some time and continue to consult with him despite having left the UK. Dan has the enthusiasm and energy of a young man, whilst taking the holistic “physician” approach of an old school family doctor, equipped with the most modern insights and technology.
Dr Jain was great. Expert knowledge with practical advice
