I Have Had Severe Bone And Muscle Pain For Several

I have had severe bone and muscle pain for several years now. Several in my family have lupus but my blood results do not show lupus. It seems to be getting worse sometimes my legs wont bend normal. They have diagnosed fibromyalgia but some of my symptoms dont match up. No one wants to treat it and though I dont really want to die, I can no longer endure this much pain. I am not sure what is wrong with me or where to go.
