I know this will sound odd but have you seen a natureopath Greg? I spent 25 years having various chiropractors beat the crap out of me for temporary relief on my lower back until I would make a wrong move and be back at it with them again. A friend I played hockey with said he could likely cure me. I was skeptical, especially with the "squeaky" thing he used to pinpoint the problem area but that was about 14 years ago and have not had a problem since

even though my weight has about tripled in that same time frame!

I also have some issues with my right hip and is another on my todo list.
