21 with BACK problems?!

So when I moved here in August I started to feel a pinch in my lower back (a feeling which I have gotten before but usually goes away after a few hours). After about 3 weeks it finally went away. The feeling came back at the beginning of December, and since my new years eve stuck in airports the pain has only worstened. It started to affect my sleep, work (standing), and pretty much any postition I could possibly be in; not to mention, my hip was hurting too.
I finally decided to go to a chiropracter, which I had been avoiding because I had never been. Well he could easily feel swelling and tension in my lower back and on the whole left side. He showed me pictures of spines like this one:
He took xrays and adjusted my hip and told me to come back the next day. Well they mentioned there would be soreness from the adjustment, but it just hurt more and more. I went back to look at the xrays and my 5th lumbar vertabrae is pushed forward kind of like in the picture. And the little tip thing on the lumbar isn't really there for some reason (he said I was probably born that way, however my mom said I got xrays when I was little and that didn't show up like that). My left hip is more narrow than my right and is pushed outward. So of course that's where the strain and swelling is coming from. How I'm supposed to fix it? I don't know. What did I do to make it hurt all of the sudden? I have no idea. Will I most likely have problems with it for the rest of my life? Yes. Am I scared to get pregnant now because I'll probably be on bedrest all the time? Definitely. He wants me to go back more and get my hip adjusted but if that won't fix it, then I feel like it's just going to keep adding up and be a waste. So I don't know what the heck to do besides ice it, and take vicodin. The end.
