Thanks for query.
Your friend is having soft tissue infection
on face,spreaded on nose.
Clean the lesion with betadine
lotion and do the dressing with antibiotic cream properly and daily.
Take antibiotic course for 5-7 days.take anti inflammatory medicines.
Swelling in the throat is due to enlarge lymph
node due to this infection.
If it is not cured,consult surgeon.
Ok and bye.
