Hi
, i think i can actually help with this one, since i was 9 (im 20 now) i have suffered with chronic UTI's and cystitis. I generally get at least once a month. Do you have any symptons sorry to be graphic but low stomach pain, intense burning when you have a wee, lower back ache, going to the loo every couple of minutes but not being able to pass much?
If you do then chances are you have a water infection (UTI) but you can also have an infection without symptoms. The only way to clear up the infection is by taking anti biotics. the symptoms can be controlled with over the counter products but i find that if i only use these it wil return time after time.
They may need to do a second test because a UTI can sometimes have very low levels of bacteria that dont always show up on a test or may be difficult to see exactly what it is.
You shouldnt worry, they are very comon im actually on another forum for UTI sufferers - i have a thing about forums lol.
Its also very common during pregnancy but iv noticed its not really talked about on here for some reason.
I hope you find that helpfull if i theres anything else that you want to know that i might be able to help with please ask.
please dont worry, all will be sorted soon
only three days and I will know more. Thanks for your advise
