Hi. Not sure whether to post this under Immunological or Hypersensitivity and Intolerances. I saw an Allergist recently and mentioned that with ME/CFS it may be common to have allergies and sensitivities to foods, odors, and chemicals. (It's on the CDC site. ) He asked me why that may be (genuinely wanted to know). I'm foggy and I'm not up on the research. (When I can I need to research this more myself.) I was wondering, so I can share with him, what are the reasons or hypothesis? Any good research as to why? It's a huge problem for me, and that things aren't showing up on allergy tests. It doesn't look like he can help me. Need to figure out what to do next. I'm in a lot of trouble with this.:/ Thanks for any information to share with him and any ideas for me.
