Hi,
I think what cured my PATM by 99% is betadine antiseptic wash. Before wherever I go people around me cough or sneeze but after I regularly use betadine for at least a year I can do grocery shopping without reactions. I get most of the reactions when I just bathed and got out. I don't get reactions from my family.
I bathe in betadine then soap. It's ok if the wash doesn't not bubble up and for soap unscented is better. Then I rub like I have grease on my skin. I should also wash my hair with anti dandruff shampoo else it will smell. I also use alum stick for deodorant.
As for my diet, I eat almost anything, even junk food. But I feel "sticky sweat" when I eat bread. I drink probiotics everday (Yakult). I rarely drink softdrinks and liquor. I also never smoked.
I think certain chemicals disrupted out natural microbiota, especially on the skin, like harsh soap, pesticides, deodorant, anything we smell or put onto our skin. Or it could be gut problems.
