Chronic Pain and Frustration: Seeking Answers

For the past 6 months I have experienced severe chronic pain. At first it started as feeling bruised all over. Now it has progressed to affecting my psych (ex constant waking in the night, 3 hours of observed sleep average, tremors, head shaking, and something I describe as an attack of immense pain and confusion). My sed and RF factor is on the increase, but is still considered normal. I have a family history of arthritis and autoimmune diseases. I have had X-rays that prove degradation in my SI joints and inflammation in my hip. I feel it worsen everyday, and for the last 3 days my knees have been clicking and my hips are cold and stiff. They refuse to treat me, denying my pain and my frustrations. When I got a second opinion they were heavily concerned. Right now it is getting blown off, and I have started to have to use a cane to walk at night (when my pain is most severe). Am I right to be worried? I was in pain all over years prior, but marked it up to my battle with depression (which is currently at its best in a time so frustrating for me). That could be fibromyalgia, but I feel this is something more serious and needs treatment. Should I seek another doctor, the rheumatologist I seek currently blows my conditions under the rug and is retiring shortly, so he is not concerned in the slightest? Thoughts?
