I am itching like crazy,there is no sign of parasites or bites.It seems to get worse at night.When I am around other people,they begin to itch also,mostly on their face,neck,hair,ears,and nose.This happens at work,in line at stores,I make the people in the waiting room itch and some actually change seats to move away from me.My general physician had no answer and gave me PERMETHRIN 5 percent and said to apply neck down and leave on for 12 hrs. every 3 days and i did this 3 times.It helped the first time(I thought)but not the next 2.I went back to doctor and suggested to apply more daily.He decided I should see a dermatologist and I saw 2,both said there is no evidence of parasites and ignored my suggestion that I am contagious.They both perscribed antihystamines and hydracortizone.I am itching slightly less but still make anyone I come in contact with itch like crazy.I have laundered all items daily,covered matresses and pillows with bed bug and allergen covers,changed all soaps to free and clear types,put majority of clothing and linens in large garbage bags,and done numerous home remedies plus anything and everything suggested in forums.The last place I lived had a very bad mold issues but this didn't start until almost a year after leaving.The itching feels like flea bites sort of but I have no pets or visible bites.I don't know where else to turn.Please help in any way you can.I am at the end of my rope and don't want other people to be infected or go through what I have experienced.Thank you and I will appreciate any small advice you may have.
