Yup. I know what you are talking about.
A few months ago my doctor had me go on a gluten free diet for a month, even though I had no gluten issues. My first gluten meal was spaghetti. About 40 minutes following the meal the joints in my fingers started to ache, my stomach bloated and I felt terrible.
It happens every time I eat pasta and, to a lesser degree, bread now. I avoid it as much as possible now.
Try 100% corn pasta. It taste's great and no aches or bloating.
