Larry, I'd suggest you look at the Life Extension website to narrow down the product options, then call the free Health Advisors/Wellness Consultants for additional help. Some of them are very knowledgable and they're not at all pushy. This is a great resource, IMO.
If you find a product that helps you you might then want to become a member to get better prices. Also, Vitacost carries some, but not all, LE products and they have excellent promotions.
I'd be remiss if I didn't mention magnesium for pain relief. In addition to the mineral we're all familiar with, the homeopathic Magnesia Phosphorica is useful. I keep Mag Phos cell salts, (a kind of subset of homeopathy) tiny tablets that melt in your mouth, next to my bed. If I have trouble falling asleep or wake during the night I'll take one or two of these and usually fall right to sleep. It doesn't guarantee a good night, but it has saved me many times. Use the 30C dose. Don't take with water, just let them dissolve in your mouth. Available from Amazon.
Hope you find some relief.
