Could my pelvic burn/numbness be caused from my lower back issues?

[adamconn]

I hurt my lower back playing college baseball several years ago. I never sought out medical attention because I was still able to be productive in life. It would just make my leg tingle and go numb every so often. Several years later I hurt the same spot falling down stairs while carrying laundry. It hurt, and the burning/numbing symptoms got worse. However, my son was receiving regular treatment at the Children's Hospital for epilepsy, so I didn't have the extra money to see a doctor. Plus, I was still not completely miserable. Well, a few years back I abruptly started having hemorrhoid symptoms and kidney stones at the same time. It was weird though because I didn't see or feel the hemorrhoids, I was just had severed itching in the buttocks area. I had a few kidney stone surgeries. A week after the second surgery I started having severe burning in the pelvic region and a constant urge to urinate. I also noticed an itching/tingling sensation on my scrotum, hips and inner thighs. These symptoms have never went away. I am miserable at work every day. I burn in my groin and have to pee every 20 minutes. I went to a urologist. She put me on medicine to help with frequency. It barely does anything. She also did a screening surgery to look and see if I had any damage. Everything in my urethra and bladder looked fine. She also referred me to a neurologist. I told him I think everything is related to disc/nerve damage in my lower back. He said that he thinks it is small fiber neuropathy. I have an MRI on my back next week and a small fiber neuropathy test in a few months. What is going on? Any help would be great.
