whitechinacat, Maybe you will not see this, but that sounds scary. I hope you get something figured out soon. Maybe this is some kind of food sensitivity. I know I keep mentioning this book, but it is a good one--Foods That Fight Pain has some great info on foods that trigger various ailments such as migraines, joint pain, digestive problems, & fibromyalgia. For example he lists the common triggers for migraine, in order of importance: dairy products, chocolate, eggs, citrus fruits, meat, wheat (bread, pasta, etc.), nuts, tomatoes, onions, corn, apples, bananas.
