I've had bad back pain since giving birth and was prescribed zapain, which didn't do much to ease the pain so was since prescribed naproxen, which works: but when I have a bad flare up, the naproxen isn't enough. I vaguely remember the Gp saying you can take the two at the same time, but I can't remember for sure, so does anyone know if you can take the two of them together? Or did I hear incorrectly?
