Can someone please contact me about this. I think my 4 year old son has PR. I have taken him to the doctor 5 times in the last month and this rash isnt going away. It started out as a very itchy red and bumpy spot on his neck. Then spread all over his body, arms and back. Now it is going down to his genetials. The spots itch for a few days then turn into a scar. It makes me sick to see him all scarred up like that. The doctors have given me all kinds of creams to use on him, such as Triamcinolone Acetonide 0.1%, Desonide Ointment 0.05% and Permethrin Cream 5%. Nothing works. They now have referred us to a pediatric dermatologist. I am in the military so we have to use military doctors. I pray they tell us what it is and give him the help he needs. Thank you for your time.
