<s>[INST] The left side of my husbands face is swollen. The left side of his nose, left ear.cheeks and lips. Touching the upper lip is very painful..Does this sound like a staph.infection. He is an Alzheimer s patient, which I know has nothing to do with this problem. Send reply to YYYY@YYYY Barbara Nobles [/INST] Hello and thank you for asking HCM,you are right and this condition of your husband has nothing to do with Alzheimer's disease.  It's definitely an infection and it could be Staph aureus. Infections in the part of the head can be very dangerous, so I suggest you to visit your GP or go to ER to get medication as soon as possible. </s>
