Hi my grandson has these bumps all over his legs and arms some are very thick hard bumps and they itch him really bad. He keeps them snatched to the point he digs holes in his arms and legs. We took him to a dermatologist and they said it is eczema, but the cream he was given isn t working. His pediatrician says it is bug bites. I know a few are mosquito bites but the others always come back in the same places. How can I help him stop itching? When he doesn t itch they start to get better. I am afraid to keep giving him Benadryl for the itching.
