I have POTS, and as long as I have had POTS (4 yrs.) I have had bladder pain,bladder discomfort,bladder infections.I also have feelings like the nerves in the pelvic area are exposed. I am having a cystoscopy Feb 22 ,my doc thinks I have IC.These bladder problems have been unbearable at times,I have had excessive bleeding,and in Dec. I also had kidney stone. I am having the cysto under general anesthesia(not crazy about that). Others on the site have told me I am better off being under,cause it is not pleasant. I sure hope the dr. will be able to help.Now when I have a flair up I take pain meds. and pyridium, it does help calm down the bladder. If any of you know of any things or meds. that help, please let me know. As far whether POTS and IC are related,I cannot help think they are all my other seamingly unrelated medical problems,started when I got POTS ???? Pat
