Treatment For Pain In Neck, Back, Knee And Foot Numbness?

I have neck, back, right knee pain and numbness in my right foot. So far, my MRI says I have a bulging disk below my C6-C7 fusion that is pinching a nerve, the lower two disks in my lumbar spine are gone. All of my RA tests were negative. Tomorrow they are doing an EMG on my right leg. I have been diagnosed with post-polio, fibromyalgia and osteoarthritis. They have had me in therapy (PT) for two months and done 3 epidurals on my neck and my pain is still there. Additionally, I fell twice and had an avulsion fracture on my left little finger and a radial neck fracture on my right elbow. What are my options for a definite diagnosis and treatment?
