If it's not a UTI what can it be?

[comingupsouth]

What could cause my bladder to burn? I feel like my pelvis is on fire.
I had 5 days antibiotic ( Nitofuranton) from the GP. Painkillers don't touch it. I have had Naproxen it didnt work. Not even Zapain ( strong ) codeine.
It doesn't sting when I wee and it's not cloudy.

I tried bicarbonate of soda in water just in case.
I feel like I'm bursting to pee but I'm empty.
I use Vagifem as part of my peri menopause strategy.
Ultrasound was clear.

Has anyone got any suggestions? Or any idea of what I can take to numb the pain?
Help!

I would go back to doctors, presumably you tested positive for uti initially. In which case it will be a uti which the antibiotics haven't been enough to cure, some utis need different antibiotics.

Maybe its developed into a kidney infection. Would go back to doctors asap anyway. Probably needs more antibiotics.

I don't get urine test at GP it was done via phone call. I have had UTIs in the past and these antibiotics worked.

I'm going t try to get an appointment in the morning but of course there is no guarantee I will get one

No appointments Available at GP today, ring again tomorrow at 8 am.
Even though I rang at 8 am today.

I wonder if it's interstitial cystitis?..

See your gp they should not have given you antibiotics without testing to see if you needed them and the right kind. Some uti's take multiple doses

I'd be tempted to call 111 and see if you can see a doctor today. Some utis need different antibiotics.

I'm prone to UTIs so I think they just assumed. They have done the same for me before and they worked.
I'm not sure it is a UTI this time. It would be unusual for Nitrofurantoin not to clear it.
