Thank you so much for your quick replies! I really think I have finally found the answer to what has been taking over my body and life for the past year. The information has been very helpful. One more question, the symptoms I have been experiencing didn't show up until about 1/12 months to 2 months after the root canal. Is that normal? Do symptoms usally show up right away or do they take a while to surface? Also what is the best method of testing for levels of mercury in your body. I heard it doesn't show up in blood tests very often and it will only show up in the hair test during the first stages. Thanks again!
