It's odd that you brought up a cystic disease, I've had pelvic fluid from cysts that have burst that my doctor found recently, but again there was no further investigation into that.
I never have dry mouth. I've been hospitalized for dehydration several times as a child, before the lupus diagnosis, and even then my mouth never felt dry. It's just an overall feeling of extreme thirst.
I have an appointment with my rheumy wednesday and if he can't recommend a specialist I'm going to make an appointment with my gp and see what she thinks. Another odd thing is that I've had a chronic UTI for about the past six months. I'm not sure if any of these things go together or not but it seems like maybe a urologist would be a good start. Thanks for all the support Vee, I really appreciate it
