Hello My son Brandon woke up this morning with his lip swollen and his right side of his mouth swollen. Yesterday he said that it was a  little swollen but now its big. What is this from? There has been no change in detergent or soaps or anything like that.
Hello. Thank you for asking at Chat Doctor. I went through your history and from history first thing I will think is angioedema, although there are other causes of lip and cheek swelling like infections, etc. It can be due to allergy to some food or Chat Doctor.  If this has happened for the 1st time to him, I would suggest you not to worry and a 3-5 day course of antihistamine such as cetirizine or chlorpheniramine male ate or levocetirizine will help. Hope this will be helpful to you. Wish Brandon a fast recovery and the best of the health. Regards.
