I also had the same thing & ended up with surgery. 1.5 years later, no numbness, no pain, everything is good.
Caveat - the MRI's did NOT show that I had a disk implanting itself into my spinal cord. The surgeon earned his money digging that sucker out. He used bone from my hip & made disks, fused the whole thing and I'm good as new.
Regarding chiropractors - I saw one. It felt great for about 6 hours and then the pain & numbness came back with a vengence. I believe that he could have paralyzed me, knowing what I know about the disk & my spinal cord.
Have they done an MRI? I agree with the others about getting to the cause rather than treating the symptoms.
