<<Disclaimer: Verify this information before applying it to your situation.>> I too have had the aching knuckles problem, but only in one finger, in one joint. After the doctor found nothing wrong, I began considering foods. After much tracking, I discovered that, like Steve, the problem was linked to corn. I can eat it 4 or 5 times a week in moderate amounts, depending of course on the state of my "trigger finger." Karen
