Suggest Treatment For A Hard Lump On The Pelvic Area

I have a very hard, bony lump on my left pubic bone. It is quite painful. For the last few months it has increased in range of pain to include the bone I sit on, my hip, and my lower back. Walking has gotten slower. Things that make it worse are sitting on hard surfaces, laying on my side, and standing too long. Leaning over my bed seems to relieve it a little, and the pain is worse at night. I m stiff all over in the mornings, but I am diagnosed with fybromialgia. I ve had an X-Ray, Ct scan, of my pelvis, and MRI of my lower back with the CT showing a few scattered subcentimeter bone islands on the left pelvis, and MRI showing a bulging L7 disk. My Dr. never mentioned the bone islands to me, I read it on the copy of the report he gave me. I ve been sent away with a shrug, another new NSAID, and Buspar for the anxiety the pain has put me in. I m hoping there is a Dr. out there who will offer some advice as to what I should do next in order to get the help I need and free of this pain.
