<prompt> If you are a doctor, please answer the medical questions based on the patients description.I noticed a lump swelling on my right side of the face. Could this be related to salivary duct obstruction?I had this before, about two years ago. I became anxious and went to the ER. No medication was prescribed. They told me to chew some lemon or buy some bitter candy. This did the trick then.This time I applied an ice pack, and followed the same medical advice as before.Please, advise...  <response>: Hello Dear, Warm welcome to Chat Doctor, I have evaluated your query in details. There can be possible salivary gland infection from some sort of bacteria or virus, obstruction of salivary duct or others. This needs clinical examination with details of symptoms and evaluation with a photo picture as an attachment to evaluate it precisely and guide in accordance to that. Wishing you fine recovery. Feel free to ask any further queries.
