Is Juice Plus one of the pyramid sales deals? If so, your relative may be selling it and want you to try it for that reason. There was one a few years back that I tried, called SeaSilver. It
seemed to help me have more energy and less pain but I couldn't really tell for sure. It was about $35 a bottle back then. Later they were sued for making false claims.

There is a lot of info available about inflamation and inflamatory foods. You might want to check into that. Someone here on this forum found a website where you can check the inflamation factor on over a thousand different foods. I can't remember who's post that was to give them credit, I am sorry. The website is a good one. Basically, fish is good, hot peppers are good, sugar is bad. When I find that post again, I will let you know.
As far as things you can put on the sore joint, I am experimenting with DSMO. I mix it with veterinary liniment. Does work, but smelly. Also, DSMO is a chemical that has its own set of possible problems, so use with caution. It is available at the farm supply store, next to the liniment. Also, arnica is a good pain reliever.
Dietary suppliments: boswellia for pain (frankinscense), ginger and tumeric for inflamation.
I am not qualified to diagnose you, of course, but your symptoms do sound like my RA.
I have been told you don't have to show a high "sed rate" to actually have RA. It is an indicator, but not absolute.
Good luck. Hope you find relief soon.
