If you are worried about inherited back problems, please DO NOT go to a chiropractor without first being seen by an orthopedist that specializes in back problems.
My 16 yr old daugther has spina bifida occulta that was diagnosed this past April by an orthopedist that specializes in spine and back problems after having been wrongly diagnosed by a general orthopedist, family doctor, pediatrician and chiropractor with scoliosis. He did a very thorough exam including an MRI and full body bone scan before making any decisions about her care. She went from describing the same type of pain you are experiencing and difficulty walking to minimal pain under his care. I will never, ever take her to a chiropractor again even though I have seen one myself and was very happy with my care.
Some of the things he looked for on her scan and MRI were ankylosing spondylitis and herniated disks.
He actually sent her to a pain management specialist for treatment followed by physical therapy. Before we went to him she was in too much pain to do the physical therapy at all and was wearing a back brace 24/7 at the advice of the physical therapist who originally worked with her. She no longer needs the back brace.
