Have Back Pain. Have Limited Movement. X-ray Showed Extra Vertrabre. MRI's Show Moderate Arthritis, Herniated Dics And Spinal Stenosis. Guide?

Question: I have had back pain since Jr. High School and has continued to get worse as years go by, I'm 47 yrs. old now. I work M - F and keep little ones in the family most weekends. I want to contine to work until retirment. I have very limited movement / range of motion in my neck & back and that is a huge concern - it affects so many simple things like changing lanes while driving, cleaning myself properly in the bathroom (important concern - it's been over ten years since I was able to reach around back to clean myself and now my back is so stiff that I can barely reach between to clean myself), etc. I've been told different things by different doctors, it's like I'm having to try to figure this out on my own. One X-Ray showed I have an extra vertrabre, could that explain why I've had back pain since around the age of 13? MRI's show moderate arthritis, herniated dics, spinal stenosis - cervical and lumbar, DDD but yet I don't have an answer as to why I hurt all over?? Most all of the time? My doctor acts like it's in my head either way I need to know what kind of tests or questions that I might ask my doctor about that might explain my all over pain and help me get some relief. I know the difference in nerve pain because I experience it and have injections for them but this is different, it spreads from my neck down my back & across from shoulder to shoulder. I'm so stiff / limited movement that I worry I might not be able to care for myself in the future if I don't figure this out and get the right help. Suggestions? Please help.

Thank you. I have some more questions....what can I do to increase my range of motion so I will be able to continue to function years from now? I currently do some yoga stretches. I had my family doctor do blood work for inflammation - CRP results were a 9 or .9?? is that in normal range? She really didn't explain it to me just said that was the results for inflammation. My pain management doctor seems to discount my complaints like I'm imagining it. I have trouble talking/expressing myself to the doctor / any doctor when I'm in their office for some reason. My complete list of complaints: headaches, pain runs down left arm, low back pain that runs down both legs, in addition to the ROM problems. I just need to know honestly if the reports correspond with what I am saying? He seems to think it's not that serious but I would hate to feel what he would consider serious.
