Hi i think we all have that worry Northbear especially as we are often worn out and emotional with the pain by the time we get to see a rheumy...take a deep breath and maybe make some notes of points you want to cover as its easy to get side tracked and symptoms you want to raise get pushed aside.
I wish you luck..if possible take someone in with you to listen to replies and support you getting your points across...let us know and welcome...i just read your other post ..it could be fibro as we do get bladder symptoms although ive not heard of bed wetting but then maybe people are a bit embarrassed to say...please make sure you mention this as it should alert the rheumy to ruling out other conditions.
take Care
