Thanks for your response. It is helpful to me to know others have been through the craziness. I'm going to print the tests you had done and ask my doctor when I seem him Friday. I will also find out my CT results on that date. I have an appointment with an immunologist at the end of July. The RAST test is a blood test. I interpreted it to be a "snap shot in time", meaning I think it tests for immediate reactions only.
The dental work I had done involved two crowns (and it seemed the temporaries were on forever), drainage of a small abcess, and a root canal. I initially thought my feeling funny and nausea related to the temporary glue on the permanent crown because they started about the same day.
Thanks for all of your input. I tried some homemade bread, but it didn't sit well. Then again, I had just gotten back from drinking all the CT stuff....
