Trish,
The H1N1 and regular flu contain mercury, a known neurotoxin. There is a small percentage of regular flu shots that are mercury free but they need to be specially requested, otherwise you probably got the ones with mercury in them in the form of thimerosal. For some reason all other vaxes in the U.S. are pretty much mercury free except these two, even though you can get them in other parts of the world mercury free. It is my hunch that the problems you saw, especially the onset after the vaccines, may have a metal toxicity connection. We saw the same thing after a vax, but ours was a mercury free one. That worked up my sons' immune systems and triggered the onset of celiac as far as my doctor and I are concerned. (Hard to prove that definitively).
There are all kinds of tests to check for metal poisoning. There is a treatment protocol that is pretty common-- DMSA, it is the same medicine given to kids in the 1950s for lead poisoning, only it is given more often due to the nature of mercury vs lead. Some tests are more reliable than others.
IgG can render different results than an IgE. IgG points to food intolerance moreso than food allergy. IgE is a histamine type reaction to food. IgG is digestive, mood, general malaise type thing.
Screen sensitivity is common. With metal poisoning, especially mercury, there can be a major zinc deficiency because it gets depleted. This is also common in digestive disorders. In our personal experience my son had major light sensitivity and screen sensitivity when his zinc stores were really low. At one point when he was sick and ticcy we had him tested and his zinc was so low he was put on 50 mg a day (at age 3, which is a phenomenal dose). All that is a thing of the past now that his gut has healed. I don't know if you have done antibiotic treatment for Pandas but it could lead to fungal overgrowth issues. We did not have Pandas dx. We weren't fighting strep but actually a major fungal infection that was systemic. Antibiotics will aggravate a fungal overgrowth problem and can actually make the symptoms worse. It is possible to be fighting both strep and fungus. When you upset the flora the organisms start to compete for territory (bacteria and fungi are in all of us in a small amount-- it is normal).
We saw a touch of OCD at onset. Our son had major anxiety. We did nutrient level testing and found major nutrient deficiencies. When we changed the diet and the gut healed they slowly corrected. At onset we were doing high doses of everything.
