My son is almost 4 years old. He had bad cold and coughing really bad. He recently got his adnoids removed. At the same time they removed his tonsils and placed new tube on his left ear. His left tube fell off prematurely. His is on albutoral (hope spell right). And i gave him tydenol and motrin also. His eyes got red all of a sudden. I thougth it was pressure from coughing. I saw tear mix with blood coming out of his left eye. Is this normal ? I am really worried.
