Bluebird, ask urology if you could, in fact, have interstitial cystitis (aka painful bladder syndrome) and if they say you would have hunners ulcers if that was the case, that is not true. Most cases don’t.
I have a lot of experience of this condition unfortunately! The normal ‘Teflon like’ lining of the bladder becomes compromised and is very painful especially as the bladder fills up. A constant feeling of having a full bladder even when it’s almost empty is one of the symptoms.
I hope you haven’t got that as it’s challenging but there are various treatments that help manage it - antihistamines are one (didn’t work for me though) but diet is one of the things that most find helpful - and making absolutely sure, via proper lab testing, that you don’t have an embedded UTI (some are hard to find - I never accept a negative result if I’m in a lot of pain) long term low dose antibiotics can help or, better still, a drug called Hiprex but you need to be infection free to start that. Google interstitial cystitis and see if you think it could be that. (That could look like excema) if so, ask to be seen by someone who has experience of treating that condition. Not all doctors have this, as although it’s not rare, it’s not that common.
