This is a picture of one of my rashes , I have strongyloides ,you mentioned insomnia at nite and tired during day , another sign of a possible parasite (strongyloide infection) do you have itching and wiggling feeling in skin especially butt ,groin area. Do you have an itchy throat at nite or dry cough. Do these rashes come and go . It's almost a full moon and my rashes were the worst during full moon . Strongyloides is sometimes associated with Lyme. Let me know if this sounds familiar .
