Naproxen
"My back pain started right after the kidney infection and tried X-ray, ultrasound, and therapy (still going for therapy), and physical massages. I avoided any medicine until I felt feverish one day and took one Advil pill. As I was sitting down comfortably and had to get up to make dinner, I noticed drastic change that I was in lesser pain, but still in pain. I was able to move better than I have been in two months. The physical therapy was helping, but it was a slow progress due to my work environment that requires me to lift heavy things. The massages were a bit helpful, but I wanted it everyday sort of a thing to get a relief. I ended up taking 2 Advils, but it wasn't enough for me. I told the doctor and she gave me this! No more pain!"
