my son has eczema and in the areas that usually are affected, legs, around the under knee etc, he has been getting tiny skin colored bumps that have turned into tiny red scabs all over his thigh, calf and around the knee area. I took him to a walk in clinic and the doctor said it is not eczema but could be mosquito bites, or scabies, or bed bugs, but nobody else has this symptom. And he told us to continue using his eczema cream for a week and if no change then come back? Any thoughts.
