I have little tiny black dots on my skin that can only be seen with magnifying glasses. there are also some on my son he is 10 yrs. old. sometimes on things i have touched even things in the fridge i find bigger ones that are round and flat. then sometimes there are groups of brown things on things i touch that are like melted together. Tonight i took a bath then shower. after that i was being bitten so bad i screamed. I looked and a black thing was there. i can take a paper towel over my skin and get usually 20 or more of these in about 10 min. I have been treated and had a clean skin scrape from a derm doc. we have bothe treated with permetherin cream and dont wear the same clothes twice. i am on neurontin for sensitized nerve itching from derm doc.
