I could not find a forum for diabetes complications except the one for eyes. There should be one for kidneys, and one for "Other Complications".
Twenty years ago I was told by an arthritis specialist that my newly diagnosed rheumatoid arthritis (RA) was caused by my diabetes. I had had Type 1 for over 40 years at that time. I wonder if doctors would still say this now. Here is a site I have been reading:
NFB - Arthritis and Diabetes: A Common Association
Have any of you who have both diabetes and arthritis been told that your diabetes caused your arthritis?
