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,
