both pictures were taken today ,the rash on my arm is about a week old rash , the picture of my left buttock rash started Friday with the full moon these are the only 2rashes I had in the last few weeks . Looks a lot like shingles but I am battling strongyloides and these rashes use to cover over 50 percent of my body 24/7 for many months after drs misdiagnosed me and gave me steroids . But the pictures I took today resembled the rashes I had before steroids and was seeing a dermatologist and tropical disease dr . And Those 2clueless specialists gave me steroids and flagyl . I was tested for shingles and many other diseases and when they didn't know what I had they assumed a Protozoa of some sort . So if your rashes resemble mine you may have something similar to mine . Severe headaches are a Herxing symptom from albendazole and severe is not a strong enough description . My wife has taken all my meds and has done some of my protocol in the beginning of my treatment to make sure she wasn't infected by me . She never had 1 headache or Herxing symptoms except 1mild case of diarrhea 1day . She has done many doses to make sure she was clean of parasites , so what I am trying to say is if you are taking parasite meds and you are Herxing you are most likely infected. Strongyloide rashes resemble shingles rashes , you can bing images of strongyloide rashes . Happy hunting and wish you well
