Along with seeing a Neurologist I would also see a Urologist if you aren't already.

I deal with the IBS and Gastritis. Those I think come from having part of my intestines removed. I'm opposite of you on the other part. I deal with constipation.

I have Interstital Cystitis and I go too many times along with pain.

I will say they do have some good treatments out to help people with bladder problems also so once you get to the Neurologist and it's not connected to the numbness in your legs then think about seeing the Urologist.
