It takes months to calm a body down from exposure to allergens. Once I knew what to avoid it took my burning feet 6 months!!!! No more foot pads burning. Heavenly.
Look up off gassing of chemicals. For me my True Test showed a major reaction to Mercaptobenzothiazole, MBT which is used to blend materials like poly/cotton, elastics, spandex and memory foam and a host of others. You have heard of latex allergies, that is another element in rubber and MBT comes from rubber. Until you get tested get a large piece of vinyl (clear heavy vinyl is sold on line).Vinyl is free of MBT and latex. Or you can order a large plastic bed pad, as used for bed wetting. Cover your mattress, then put on a thick pad or 2 of 100% cotton or a cotton cover with 100% polyurethane fiber fill (no blended materials) so sleeping is not too hot. This vinyl or plastic will block the off gassing. With MBT or latex allergies you can't even share your laundry loads with family members who clothes are blended or elastic as this contaminates our clothing.
Got to lawsuits about mattress chemicals, memory foam allergies, Tempurpedic Memory Foam Mattresses is a major offender as well as others. Loads of folks are allergic. 100% cotton sheets or blankets or pajamas do not protect, they are porous. Also our skin is porous. These off gassed chemical enter inside our bodies, not only while breathing but though our skin raising our histamines throughout our bodies.
