Hi Lois. Welcome to NT. This is a wonderfully supportive place.
I have friends with MS, but that's the extent of my knowledge. I have pain where you describe but mine is from inflammation in my sacroiliac joints. I used to get epidurals because they thought the pain was from the problems with my discs in my lumbar region. As soon as they started the SI injections, I found much more relief.
Here is the MS forums link.
