You really need to see a spine specialist; either an orthopedic surgeon that specializes in spines or a neurosurgeon that specializes in spines.
There is really no way to tell you what types of treatment are possible without knowing what is wrong.
You have to have a diagnosis first.
What you can do is try ice on the area that is hurting you. That can decrease the pain by numbing it for a bit and decrease any muscle swelling that may be going on.
If that doesn't help, then you can try moist heat on the area that hurts.
You can also try some ibuprofen to try and decrease inflammation.
Beyond that, there really isn't anything we can tell you without knowing what is wrong.
