I took my 10 year old son to pediatrician last wednesday because he was very congested and had cough. I was just recovering from bronchitis so I was worried my son had caught the same. Dr said his ears and lungs sounded fine and said to continue to take otc meds such as tylenol, dylsum, and mucinex. My son has no fever but fri,sat, sun, mon and today - he is very sleepy. Other than being exhausted, he has no other symptoms besides lingering cough. I m concerned because I feel he should be recovering now.
