Hello,
I agree, you might want to get the hip x-ray'd and MRI'd. Several yrs ago I had a multi-level laminectomy (and foramenotomies & discectomies) from L3 thru L3. After the surgery I started feeling pain in what seemed like my hips/pelvic girdle. Since I wasn't long out from surgery, my spine surgeon sent me to his group's hip specialist & I had both MRI'd & xray'd. He mainly wanted to check for osteonecrosis, but it turned out I only had mild arthritis. My surgeon thought it was hip related, the hip doc thought after the tests that it was spine related. A month or two later I had problem at L4/L5, had an MRI, and that noted mild disc bulging and mild narrowing at L1/L2. Nothing was ever mentioned about it because it didn't appear that it could have been causing me any problems. Over time, this pain has worsened, though, and normally feels like it's in both hips, my groin, and across my entire pelvic girdle on both sides. I also get bad spasms as well as muscle cramps. For myself, Soma has helped control these quite a bit. Anyway, my Rheum kept telling me Fibromyalgia and hip bursitis. I saw bursitis as diagnoses on my med recorRAB, but strangely he never me actually told me that or offered any suggestion as to how to treat bursitis. I told my last PM about it, he did some physical tests like moving my legs in different directions and thought it might be my sacral area. (I have been diagnosed w/ sacroilitis as well by another doc and I do believe I probably do have this)
Then we get to now (well since this past October) I had to go to a new PM due to insurance. He sent me for all brand new x-rays and MRI's (oh what fun that was :::eyeroll::

Anyway, my lurabar MRI's showed a few disc herniations with a massive one at L1/L2. My pain doc thought the dermatome for that ran to the hips/groin region. So we did some ESI's at L1/L2 and what do you know.....suddenly almost all of the nerve pain and spasms I had in my hips/pelvic/groin areas was gone. The ESI's along with my meRAB I had almost no pain. This is since late '06. The only problem is, the ESI's don't give me any lasting pain relief. They last about 2 weeks, then I'm back to where I started. At it's worst, I was also getting stabs of sharp nerve pains in the front of my left thigh down to about my knee.
I also know exactly what you mean about you hip feeling "out of place". Boy i can relate to that as I get that on and off with my left shoulder. I have literally asked people to pull my arm and push onto my shoulder. Now I know it was due to severe muscle spasms. I've also felt like that in my hips from time to time. I don't know if this is normal or not, but my hip joints (used to anyway) be able to move alot, not sure if they were actually coming out of place, but I could make then do it. When I have all this pain, I find myself trying to do that thinking that it will get "unstuck" or something.
