my lo been stung by bee! T. T we observed him, bring him to pd. the pd said it's OK to see his face swollen, just observe if there is fever or blood in urine. still very worry.. any ways to reduce the swell on the face? look at him.. *heart pain

Oh, poor thing. I'm not sure if your PD, prescribed antihistamine. If not, then it should be fine. You can also apply ice to the affected area tor reduce the inflammation. It will go away in a couple of days. It may or may not leave a little bruising in the affected area so do not be alarmed. It will also go away.
