Two points. In talking with people with BAV and aneurysms and the like I seem to see more people than I would expect with arthritis. One friend had a stroke at 51, she had arthritis. Maybe there is some connection between heart issues and arthritis isssues, I do not know, but I wonder.
Secondly, I have talked online to a few folks that have claimed that they were able to at least improve their arthritis by watching their diet. One book that keeps coming up is "A Doctor's Proven New Home Cure for Arthritis", written by a DO in the 1970's. I have no clue whether that works or not, but I pass it on for information.
