I"m going to say a lot of your symptoms are similar to the ones I had when I had allergies. I"m allergic to chemicals (it was awful being around husband during chemo, I had to wear a mask and get a filtration system), formaldehyde, mold. I suffered for 12 yrs on antibiotics due to sinus infections but those symptoms are very similar. just a thought.

I changed my diet and my allergies all except the chemicals went away. no sugar, no gluten, no dairy. works better than antibiotics. just sharing my experience as i know you are trying to put the pieces in a puzzle right now.

best wishes.
