Replying to Tethered spinal cord? Help

Ok so here is the deal i was born with one of my spinal cords tethered to my back.  I had surgey on it when i was only a month old, and the doctor told my parents I will be normal and good to go for the rest of life.  I am now 16 and I have like a big scare and all and just recently i have had alot of pain around that area.  All the pain started to come During this years wrestling season so i went and saw a specialest and basically he said there is no way of telling that it reteathered without surgey, so i have no idea what it is.  He told me i can never wrestling again, because of fear of loosing feeling in my legs.  I am trying to see if anyone else out there has the same thing or any info.  I hope I am not the only one and would like some questions answered.  Thank You
