My 4 year old has the same thing. I am taking him to the derm on friday morning. I'll let you know if I get the same vague answer or if he says something concrete. He is already on prednisone for an asthma attack that happened on Saturday and the bumps on his leg don't look any better. He eats spinach every night because it's the only vegetable he will eat. I hope it isn't parasites from the spinach. What are we supposed to eat now if everything could have parasites in it????
