Severe back pain

Hey all, I need help... My lower back pain has gotten so bad I can't walk, roll over in bed, nothing. It's not even cramping just pain. My sciatica is bothering me as well. I'm completely miserable. I'm only 5 weeks and I see my doctor on Thursday for the first time.

I refuse to take any medication until I see my doctor but the heating pad alone isn't helping.

Is this normal to feel? Anyone have any remedies for this?
