I have recurrent UTIs but the latest one just won't go away and the drs don't believe it is a UTI as they cannot grow any bacteria. Blood tests all fine, kidney scan fine. Symptoms for 2 months are constant headache, going to toilet all time, feeling severely sick constantly, dehydrated in night, unable to sleep, shivering, sweating in night, lower back pain. I did have cloudy urine at the beginning. I also have dull ache down below and stabbing pain. Have had 3 courses of antibiotics which each time improve my symptoms but after stopping them all the symptoms come back. Seen a urologist who is adamant it's not a UTI as the bacteria would have shown up and it would have cleared after 3 antibiotics. I have tried searching for Urologist in East Mids who specialises in recurrent UTI/lower UTIs/upper UTIs and who has a broader view of UTIs rather than the NHS guidelines like some of the London specialists do but not having much luck finding someone. Any recommendations?
