You will have a lot of support here as so many of us share at least some of your neurological symptoms.
Please note that pinpointing the exact "cause" may be rather difficult. Your neurological symptoms may actually be the result of several different factors.
My neurological issues affected the bladder, but primarily my bowel, mobility, and pain. I went through several doctors before narrowing down my medical condition more accurately. I finally reached a physiatrist who was able to analyze my back and pain issues and a spinal cord rehabilitation specialist who fully understood what was happening with my bowel issues. Unfortunately, you may need to be patient.
Most of my neurological problems appear to be the joint result of traumatic injury, stenosis (narrowing of the nerve channel in the spine) in several places, and sacroiliatis (sacroiliac joint inflammation). And, of course, I am no longer in my prime.
Have your MRI scans been done yet? They should at least narrow the search for the factors affecting your neurological symptoms.
The changes in incontinence may give some hints about the spinal levels possibly involved.
Good luck with all and keep talking with us.
