Swollen lymph node under chin and left eye lid swollen and very painful. what do i do?

Could be a sty : It may be an early sty. It should be one eyelid not both that is swollen. If one the use of warm compresses four times a day for 5-10 minutes for a couple of days should help. If both lids are swollen it may be preseptal infection and you should see a doctor as you may need antibiotics. If the swelling doesn't resolve in a 2 days or you are running a fever see a doctor.
