Moto, nerve injury help

Hey guys, I remember reading a while back about a some of you guys having nerve issues. Pain down the leg and such. I'm looking for a little experience. I've had a hard time getting an appointment with the neurosurgeon. Here's what's up.

Like most mxers, I've had my share of dingers. About three years ago I broke 9 ribs, collarbone, shoulder blade, T-1, and tore a big hole in my left lung. When I came to and got out of the hospital, after a couple of months I was left with a numb spot about the size of the palm of my hand on my right hip, around back, just above my belt.

That rocked on about three years and suddenly, about three months ago, it started growing. It first spread to the middle of my back, then around to my belly button. That took about a week or so. Then it started down my leg. In another week or two it was about six inches down my leg and over to my crotch.

Another three weeks and it has now gone down below my knee. It covers about two thirds of the circumference of my thigh most of it except my ham string area It was annoying until it got below half way down my thigh, now it feels like my thigh is weak and sluggish and my knee feels like it has fluid on it all the time.

Before any of this spreading I would get pain down the back of my leg, deep, and buzzing from time to time on my right hip like my cell phone was going off. Now, nothing.

Any of you guys had experience like this? Prognosis? Cures?
