Unfortunately most family doctors just are not knowledgeable about anything greater than the most general of medical conditions. That's not a disparaging remark about PCPs, just the fact of life. The human body is a complex machine that is often difficult for a specialist to navigate, not to mention to a doctor who mainly gives flu shots and fixes sprained ankles.

I would highly suggest to have him/her refer you to a neurosurgeon for a second opinion. I'm quite surprised that he didn't do that right off the bat if you were having problems with your bladder.

Obviously I am not a doctor, but a few of you symptoms coincide with what I had gone through. That is, a part of your spinal cord is being "pinched". That is nothing to take lightly.
