There you go . A new one for me. There are a billion reasons why something that seemed to not matter in the past suddenly sets off our weakened immune system. One guy felt a weekend of excessive exercise set it off. Who knows? Medical field does not . I thought maybe OCD , type A personalities. But it doesnt hit all of us. It seems our immune system is in sort of a perfect storm. Along comes RMSF or covid vaccine or to much gardening and wham. Our immune system goes crazy trying to fix it. It could be we are being poisoned by the jet trails.. 🙂
