I took Mobic for a couple of months a while ago. Honestly, it did nothing for me at all except upset my GI system. Relafen and Voltaren upset my GI system as well, but they worked great on the inflammation. Of course, NSAID therapy is so individual for everyone. What didn't work for me may very well work for your husband. The only way to know for sure is to try.
Best of luck,
I have taken Mobic for over a year. It worked quite well for many months. Unfortunatly I developed an allergic reaction to it and my pain in the back increased considerably. It was several weeks until I pin pointed the Mobic as the cause. After a couple of week of no MObic I am feeling better. Still in pain but not the hot seering pain in the back.
