myrosiedog, this obviously isn't a cure-all, but I would recommend that your husband try fish oil capsules. I take them to help with the symptoms of bursitis in my knees and they do make a difference. They've also caused the ganglion in my right flipping-the-bird finger joint shrink. My MIL also took and was helped by them for rheumatoid arthritis. If he does decide to give them a try, I've tried cod liver, salmon and halibut oil and found that the halibut oil was most effective.
Again, they won't magically make everything all better, but they can help alleviate some of the discomfort.
