Near the start of January I started with UTI symptoms (pelvic pain, urge to urinate etc.) Drank loads and took OTC sachets and after 3/4 days it eased but didn't really go away completely.
I phoned the GP and they prescribed 3 days of nitrofurantion. The symptoms got better but again came back a couple of days after stopping the antibiotics.
.
After a bad weekend, I phoned the GP again. Told to drink lots of water and it would get better. It didn't.
Phoned GP again. They wouldn't prescribe antibiotics until they'd sent a sample off.
But test showed no infection so no further treatment (by text).
Phoned GP again as still had bad symptoms.
They sent off another sample on Thursday. They did prescribe 3 days of nitro but I was told not to take it until tests results were back or if I felt a lot worse.
The symptoms were bearable until Sunday but then got quite bad again so I started antibiotics. Finished them yesterday.
Yesterday evening and this morning I felt better physically and mentally than I had since the start of January 
This morning GP said second test also negative for infection.
This afternoon symptoms started to come back
.
Phoned GP again.
They won't prescribe more antibiotics as there was no infection indicated - but surely if the symptoms get better with antibiotics and worse again when I stop taking them chances are it's an infection?
And they said it can't be a uti as it came back too quickly (30 hours). But 3 days is only a short course of antibiotics so if it hadn't completely gotten rid of the infection it would come back?
This has all been by phone and various GPs.
AIBU or is the GP correct and it must be something else?
