October 2020 I bought 6 tee shirts. When the came, I put 5 in the washer and made the fatal mistake of wearing a dark green shirt to bed with electric blanket. Dark dyes are toxic. Clothes should come with a warning. I started itching the next day. Thought it was dry skin because of hot air heat. Within 2 weeks I was broke out front and back with painful blisters. My friend, a dermatologist of 30 years, saw it and showed me in his medical book exactly what I had.
17 days of Triamcinolone Acetonide cream 0.1% front and back twice a day, and all was right.
From December to Mid May It was ok. Occasionally if I felt a pain like a horse fly on my back, I would put a dab of the cream on me.
Don't have to tell you this. Spring came with a hot day off and on. I stayed inside. Asked my for a Non-Steriod treatrment because Steriods thin the skin. I am using Tacrolimus Ointment 0.1%, which was developed in Japan and approved in US 10 years ago.
My drill now (august) is 63 degrees in bedroom for sleep. Wake up with no symptoms. As the day progresses with exposure to heat I only go into places which are under 71 degrees. (have accurate laser thermometer. My house is at 70 degrees. My garage is at 65 degrees when working on cars. I just bought a cooling vest from Heatreliefdepot so I can ride my bike when its 70 outside. Touch up my back with some of Tacrolimus.
