Um no. Naproxen does absolutely nothing for my pain, not even my horrific menstrual cramps which ibuprofen greatly helps. It seems to be completely inactive for me as is the case with many substances. ONLY some benzos & opiates help my back pain; I've tried nearly everything else, certainly all relevant drug classes. I should add I have a lot of spasticity/constant spasms & tons of trigger points. Lidocaine IM helps but only in one quadrant of my back. I do have some rheumatoid arthritis too but it seems pretty mild, possibly due to my diet. Meds don't help it, except Vioxx which is no longer made.
Imagine the most extreme muscle tension ever. Muscle hard as rock, all knotted up & continuously spasming. Oh & I have 3x the number of normal nerves. Though that is both curse & blessing .
