<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, I have been having some symptoms lately. I have a terrible headache, nasal congestion, and I havent been very hungry. Also, my infant has been very irritable and has a runny nose. What could be causing all of this?  <response>: It sounds like you and your infant may be experiencing an abscess of the nose. The headache, nasal congestion, decreased appetite, and coryza are all common symptoms of this condition. Well need to perform a physical exam to confirm the diagnosis and determine the best course of treatment.
