Diagnosed Spondylosis but have positive HLA-B27???

I have a lot of pain in my hips and back which fluctuate from side to side. I also get Uveitis from time to time. I do have sclerosis of the iliac bone on the left side of my sacroiliac joints. When I walk I look like a person with serious back issues as it has become tougher to walk distances without pain and remain standing properly.

I do have well-managed relapsing remitting MS and am able to walk with the aid of a cane. I walk up and down a couple flights of stairs daily to strengthen my legs. Have had MS for 23 years.

When I asked my regular physician why do I have positive HLA-B27 if I am not diagnosed with ankylosing spondylitis he tells me "because you do have it; It hasn't fully shown up yet."

This leaves me confused as ankylosing spondylitis and spondylosis are two very different conditions. Which one do I really have and how do I begin to help myself to feel less pain and begin to feel better about myself?

I welcome your hopefully helpful comments.
