Not a question but maybe some help though at 47 i have never been diagnosed I have suffered pain behind knees for years all my life, and now its up in arms. Its a burning feeling - and I believe they now think its RESTLESS LEG SYNDROME that can spread to other portions of the body.
Another thing to check is that they do not have early warning signs of a disease called Arterclerosis or something like that that hardnes ones arteries and without treatment can kill you obviously in your older years but mixed with Diabetes and this disease, you could have a short life span under 50.
this runs in myfamily and I found it by searching our family tree roots, often in men in my tree and my father was diagnosed with hardening of arteries, I think when years ago they said ARTHRITIS is WAS NOT.
Best of luck to you all
