As I studied the issue, I discovered that yucca is a natural and outstanding, safe supplement that is thought to promote symptom relief similar to steroid medications with none of the side effects and has many uses including for the joints, skin, and digestion. Yucca is given internally for joint health and digestion but must be diluted before being administered because it is quite bitter.
I thought we would try it. I surfed around and found the strongest I could find - an extract called YUCCA INTENSIVE. But it was $15 for a 2 oz bottle (with eyedropper - one drop per 10-12 pounds of body weight). Then I found out that the exact same product, made by the same folks is also packaged for pets, and sold at 1800petmeds. I checked it out and, though it was still $15, Petmeds offers a $5 off instant online coupon - just type WEBC5 in the coupon box.
Anyway, to make a long story still long, we tried it. Robin puts 12 drops a day in her coffee. And within 5 days the pain was gone for the first time in years. As a side note, she doesn't get indigestion anymore, either.
So, I though I would pass this along. I can't guarantee it will work for everyone, but it worked for Robin. If you do try it, I would be interested in hearing the results you have.
