if u have a face swelling it could be ur sinuses have infected or u may hav a nasal infection or a polyp that has broken down or ruptured. Do visit your ENT specialist immediately..... Only on examination U can decide what treatment u need to be adviced. Do not delay.
If your face has swollen up, you should set an appt. with your doctor right away. Are you in pain, running a fever? Cellulitis comes to mind. This is a serious infection. Either way, I'd go to the doctor as soon as possible to determine why your face is swollen. good luck and hope you feel better
