My friend from Italy is visiting (male, age 67) and woke up with the whole side of his face swollen. It appears like it's stemming from the area on the side of his nose? It's painful on touch. Not sure where to take him.. a dentist or a doctor. Should I just wait a few days. If it's an infection, will it get worse, or can it clear by itself. Mama Mia. Thank you.
