How To Deal With Poor Body Structure Causing Back Pain?

I have noticed this problem since I was young but it didnt really bother me until i was in high school. I saw a lot of other peoples backs and thought mine was weird and misshapen. My butt stuck out my stomach stuck out my back pushed in. I was very self conscious about it. As the years went by I noticed it hurt to stand for hours in my lower back and that I couldn't lay flat on my back without a large amount of lower back pain. I've looked into the topic and it seems like Lordosis. I never had very good insurance and I have been to a lot of not so good doctors but they all told me it was fine. It's not fine if it is causing me pain and lowering my self esteem. What can I do about this? Also when I lay down my spine feels like it moves out of place or pops near where my hips connect. My hips also cause pain and pop loudly sometimes.
