Symptoms started and where the worst for my friends son. Her daughters and she all eventually had symptoms. Her husband was always symptom free. Her son ended up in the hospital several times, but they could never find out what was wrong. She did some research herself. She suspected mold in her home. They kids improved after a weekend stay over with friends. She was able to get some testing done and found molds in her home. FYI all homes have some. This included a dangerous strain of black mold. Her husband refused to except the lab tests. They found that the highest concentration seemed to come from their basement. After a rather bad fight her husband got mad and trying to prove that my friend was crazy took a sledge hammer to a basement wall. As the drywall fell onto him so did millions of black spores and hype. It turns out the wall was completely covered in black mold. Luckily it was only in one area of one wall in the basement. They had to have specialists come in and take out the contaminated materials. The husband rebuilt the wall. My friend gave both the lab results and a small piece of the infested drywall to her doctor. This was an extreme case. Kids have been symptom free a since a few months after the house was cleaned and wall rebuilt. Sugars and carbs (complex sugars) feed the fungi aka black mold in the body keeping them alive. Starve them for long enough they die, but it takes time. Unfortunately I think these symptoms make result from several other issues, but mold might be one option. FYI kids and Mom had thrush, stomach aches diareha, headaches.
