Bladder Question(s)

I have nearly lost all urges to urinate. I went to the neuro last week. She mentioned MS, Vit D and B12 deficiency, diabetic neuropathy. So, I am doing some research until she looks over the CT and MRI's. Has anyone here had trouble with the loss of urge to urinate? I only know my bladder is full when my belly aches or I have the feeling like there is a small ball in my abdomen. I am having to check every couple of hours. Its only gotten worse. I have told the neuro and contacted my gp this afternoon. I was up for about an hour waiting for the ibuprofen and baclofen to kick in. Once the baclofen kicked in I peed 3 times and the ball feeling was gone.
Im not looking for a diagnosis. Just wondering if its something people with MS have a problem with. It started off as every great once in a while and now over the last few weeks it has gotten worse. I am really starting to worry. As much as I would like the docs to move a bit faster on this, I realize it takes time. The pain and ball feeling was excruciating last night. And the amount of times I awake with belly pain each night has increased. I havent found much on the loss of urge for the 3 possibilities I mentioned above.

The first neuro I didnt like at all. The second one I am kinda weary of because in her paperwork that was sent to her it said head ache. Yes, I get headaches, but its a lot more than just headaches. I had to go over the whole thing with her again. I imagine I would have had to do that whether she had all the info or not. I also suspect who ever sent it to her, may not have had the room to put it all down. So I gave her a second chance. The second visit with her is when she mentioned it sounds like MS. That was scary. I was thinking fibromyalgia, which I was diagnosed with many years ago and thought maybe it had gotten worse, maybe it was my diabetes. I am also thinking maybe my bladder fell after having 2 kids and a hystarectamy. But they would have found that after my abdominal ct and mri. From what I have been told, diabetic neuropathy is more painful and more in the feet?? I am not quite sure of this. Vit B12 and D I am still researching as well.
I have plans. I am also a very busy person and able to less and less as time goes on. I have a family I am having a hard time keeping after. I have a job that requires a lot of walking. This is a good thing. It really helps loosen my muscles. There are mornings that I have muscle spasms and cramps in the middle of walking. I was actually thinking to myself the other day....if its diabetic neuropathy I have the chance of losing limbs, if its MS I have the chance of not being able to use my limbs. I am really really hoping for Vit B12 and D. If its not Vit B12 and D, I will be moving up my retirement plans.
