Genital tract symptoms
Sometimes, you can also have symptoms of a urinary tract infection. These include:
- needing to pee suddenly, or more often than usual
- pain or a burning sensation when peeing
- smelly or cloudy pee
- blood in your pee
- pain in your lower tummy
- feeling tired and unwell
Symptoms can include:
- red eyes
- watery eyes
- eye pain
- swollen eyelids
- sensitivity to light
See an eye specialist or go to A&E as soon as possible if one of your eyes becomes very painful and the vision becomes misty.
This could be a symptom of iritis – and the sooner you get treatment, the more successful it is likely to be.
