My Lower Back And Left Hip Area Has Been Bothering

My lower back and left hip area has been bothering me for about two years now. It seems to be more in my hip area. When I rotate my hips slightly there is a small popping in it and it hurts on my left side when I bend over at the waist. I have been to a chropracter with no help or explanation for what it may be. It's hurts worse when the weather is wet and cold, I'm dreading winter.
