my 11 year old son had high fever for two days. he also had running nose at same time. After 3days his fever is gone he started to have pimples on his hands, his arms, and his body. The pimples are small. then grow bigger, the closed ones grow together. They are red, hard, and ichy. Today is the third day that he has those pimples. And the new ones are keep coming. today I just found out that a boy from my neighber has same pimples for a week now. Whats this problem? Please help.
