Hi Rosie. Nice to meet you. I would reccomend getting in touch with Gloria Gilbere, ND. Here is her website with links to her books and other information. She does phone consultations at a very fair price.
Have you and your son been tested for leaky gut. This can be helpful to see the degree of hypermeability present.
Was your son on any meds prior to this?
Is it possible for your son to have parasites, H. Pylori, or any other organisms present?
Are you subject to mold in your environment? Do you live near any industry, traffic, etc?
Have there been any renovations in your environment leading up to his illness?
Retrace your environment and think about potential links.
EMF is also often overlooked.
For now raw
juicing can help esp. cabbage, also glutamine, aloe vera, dgl, and a viable form of probiotics(full blend). Try a couple table spoons of flax oil daily too.
Some how, some way, the answer will come,
Hang in there.
