Craig, I know how frustrating this can be. I have been dealing with similar symptoms for the last 4 years or so. Along with the slew of tests and MRI and such, I did see an allergist, Food and environmental. I am allergic to a few foods and environmental allergies, and our dog. I do not want to get rid of our family pet, but we are at our wits end and feel that might be our next try. While I do respect opinions of others, you can not always sit around and wait for the doctors to figure out what is wrong. You know your body best. I have been through 12 doctors and more tests than I can count in the last four years. I have drastically changed my eating habits, and I am now the healthiest I have ever been, with exception of this problem. I did find a natural doctor who has done me more good than any of the other 12 doctors... We'll see how that does for me. I will keep you in my thoughts, and I hope you figure it out soon. I'll let you know how my next experiment goes! Even if it's not the same issues causing these problems for us, it is nice to have that little reminder that we are not alone.
