My 2 1/2 year old son has a swollen upper lip (not just the lip, but everything from the bottom of the nose down). He has had a cough for about a week and a half. About a week ago, he started getting a fever every day. Took him to the Dr. 3 days ago, and he has been on antibiotics since then. Fever has since stopped. Cough sounds like it's starting to get better (still bad). Should I be concerned about his swollen lip? I am pretty sure that it was swollen before we went to the Dr., but I didn't think to ask about it while we were there. Also, he hasn't had much of an appetite for about a week now. Most days, he's been eating 4-5 bites of food. (But he seems to be staying well hydrated.) To my knowledge, he hasn't bumped his lip. Nothing new has been introduced to his diet, so I don't think it's an allergic reaction. (He had these same anitbiotics when he was 15 months old) Thanks.
