I have nasty back pain for which I have taken co-codamol and diclofenac for many years. They do not help much now mostly due to tolerance probably. Just recently I have really bad ;ower back pain and also radiating around to my right side. Strange thing is that it is relieved somewhat once I open my bowels. I have no problem with constipation btw. Quite the opposite in fact. But if I dont go at least twice daily I have more back pain. Any ideas anyone?
