What skin problem does my son have??? Been to three doctors... he is so itchy?

My 10 year old started itching with lots of little bumps... the doctor said it was fleas or some type of infestation. We had our dogs checked (nothing) and cleaned his room... even removed him from it. Also, the other three of us in the family have nothing. It started getting worse so we took him to a walk in place on the weekend... they said it was scabies... treated him for that and still got worse. The small bite like marks became round flat slightly raised circles. They are on his arms, hands, legs, feet and just a little on his face and trunk. So, I demand to take him to a dermatologist. She really has no idea what it is... says a bacterial infection and ignores the way I told her it started... the little bumps were not a bacterial infection. He has been on an antibiotic for 6 days and creams, too. It does not look worse and maybe a little better.... He is very itchy and looks awful. There are NO other symptoms. It has been three weeks. Any ideas??? Please help!!!

What ever the problem is, try to get him to use a warm, damp cloth to relieve the itching instead of just digging. My wife has the problem and has had it since youth and tears her body up with the digging. Does he have dry skin? He may have hives.
Reply:Is your son having a reaction to some new type of food he has recently stated eating. What you discribe sound alot like hives.
Reply:The only other likely cause you have not ruled out is some type of allergy. So maybe a trip to an allergist? They can screen him for all sorts of allergens. You could also try giving him benedryl to see if it helps. Benedryl makes most people very sleepy, so you would probably want to try this during a time when he is not in school.
