<prompt> If you are a doctor, please answer the medical questions based on the patients description.my husband has been battling what the doctor thinks is a sinus infection he has had this for several months he also has had a bad headache. he isn t one to have them he has also had mood changes not like him at all I am wondering if this is somethingmore than sinus  <response>: My recommendation is for a full ENT evaluation if your consulting physician believes it to be sinusitis. Primarily it can be treated by antibiotic administration once a culture and sensitivity of sinus tract aspiratessuch as mucus are investigated. Corticosteroid nasal sprays are also available to help reduce inflammation. A likely cause for chroniclong-standing sinusitis could be allergieswhich would again be benefited by the corticosteroid nasal sprays or due to deviated nasal septum or nasal polypswhich are growths that are seen. Headaches are commonly seen in chronic sinusitis patients and mood changes could be correlative to long time stress dealing with disorder. It could also be advisable to try some Over The Counter decongestants for allergies such as Pseudocode Chat Doctor.
