I had a similar rash to this, all of these symptoms plus random bruising, every joint hurting, muscle spasm, cyst or moving calcium build ups moving in my body, brain feeling like it is on fire, chronic 24/7 pain and more symptoms than I can think of right now. I owe everything to where I am for finding a psychiatrist who wanted to do an Organic Acid Test and testing for Mycotoxins of Mold (other biotoxins are on there too I believe). Part of my issues are that I’m part of the 25% of the population that can’t rid it’s body of toxins.
Look up Neil Nathan MD and see if there are any doctors he recommends near you or Ritchie Shumaker, I’m thinking you could possibly have CIRS.
I had a western doctor/Acupunturist tell me this week that when your liver or body can’t process something one reaction is through the skin via rash, sensitivity etc. My dermatologist did recommend Niacin flush free which to then find out via blood work and then in my Organic Acid Test how deprived my body was of B vitamins (even though I was taking some but my gut wasn’t absorbing half or most of the things I consume.) The test then showed a million other reasons of what was wrong with me, sibo, candida, high dopamine levels, and a slew of other issues. Which all at least validated why I felt like junk and my doctor(s) and NP are helping navigate how to make me feel better a little each day.
