Oh, GREAT!

David, don't rule out anything at this point, but I occasionally have hip pain cause by muscles in my back. There are LOTS of things that can cause hip pain, much to my relief and surprise.

I have had osteoarthritis of the spine since my late twenties, I tend to ignore the dull aches that are always there and only notice the muscle spasms and other real pain that occurs regularly. There is no surgury available for me and anyway I would only consider it as a last resort if it was possible.
Hope you only have some sort of muscle spasm and feel better soon!
