Please help with lower back pain.

Patient: Hello, I am an 18 year old female. I have been having lower back pain it started a few months ago and it was just on my tail bone and it was uncomfortable to sit, but just recently the pain has gotten ten times worse, it has spread all across my lower back and it now hurts to stand after sitting and if I move my leg a certain way. Also I just have general pain when I am sitting or laying. Is there any tips you can give me before I make an appointment? Thanks
