The Oxy-Contin is the best thing that I have found due to the time span of relief, but I find that I need the ibuprofen to help with endurance with walking (cane assisted)or any other activity. I will ask my private DR. about the others, but I believe the combo that I use works well.
As to the stomach risk, I am aware and I do not use the Ibuprofen around the clock. Most days I only use it mornings and before bed.
I hope the stomach holds out, because the Naproxen stuff is useless to me and makes me ill.
