neuropathy many years later

I has a seminoma in 1975 at age 27. Had surgery to remove affected teste. Follow up treatment consisted of 3000 rads to lower abdomin.

About 20 years later I started to develop motor issues from waste down, more on R than L [R was surgery side]. Since that time it has slowly worsened to the point where now I have a dropfoot on L and general mobility issues. I have probably moved 5 standard relative to my peers mobility wise over the last 20 years.

I have gotten mixed info from dr's about the issue. A neurologist thought the problems possibly could be connected to the problem but a radiologist told me that it was unlikely connected.

Just wondering if others have any light to shed on my situation?

 

Thanks in advance
