George is a 27 year old plumber and presents with a one week history of nasal congestion and facial pain around the cheekbones. He said he had a runny nose and mild fever prior to this but has had no further fevers. On examination he is tender over the maxillary sinuses, with normal throat and ear examination and no cervical lymphadenopathy. Observations are stable.
Based on the likely diagnosis, how long would you expect for symptoms to take to resolve in total?
