Just had a family member get misdiagnosed with “delusional parasitosis” . It was a months long ordeal to get properly treated. Of course their history of drug and alcohol abuse and other mental health issues fit the profile for delusion and clouded the judgement of the physician, so it’s almost understandable but eventually, after massive infection even the doctor could see first hand proper treatment was rendered. Cysts surgically removed and antiparasitic medications administered so all clear now. Thank God.
