My issue is different from yours although there are some similarities, but I have been researching parasites in general over the last year and have continually come to the same conclusion for a doctor that can help his name is Simon Yu and he’s in St. Louis https://preventionandhealing.com/
Whatever my family has is breaking us financially so I haven’t been able to figure a way to travel to see him, but I figured I would share because I truly understand your hardships with dr’s I’ve had Psoriasis for 20 years and I know that’s not what is causing the rash on my face but I could care less about the rash because the rest of the symptoms are so much more overwhelming! But this post isn’t about that, if you’re able I would definitely reach out to this drs office! Also I had some slight relief swabbing apple cider vinegar (get ready for the burn) and following with swabbing Iodine after shower was best but I did it multiple times a day and it helped for a while… no cure but did help
