What type of allergy testing was done? Many tests are not very accurate at all, so don't rely on them too much. Another option for you might be to find someone who is very proficient at muscle testing/kinesiology. Its more of an art than science, and mainstream docs scoff at it, but natural doc I see is very good at it, and fairly accurate at determining what is bothering my body. Many people also have good luck with homeopathy, but again, much depends on the quality of the homeopathist....
