I also have lots of problems with my back, thankfully I can take celebrex w/o it hurting my tummy. Have you tried Prilosec? I know it is expensive, but when your back hurts you will try anything to make it better. When I walk, I feel relief, gotta always wear good shoes. I wear Clarks almost all of the time, I bought some on sale at Penneys last week! Hope it gets better soon. Right now it is still cool in Texas, wow! thats hard to believe. I better watch my mouth because things can change in an instant here!
My tummy is messed up too, most of it from stress and anxiety. Hope you are feeling better soon.
