The symptoms of recurrent sinusitis are essentially the same as those of sinusitis itself. Symptoms can be divided into local symptoms, which are those of the nasal cavity, as well as some systemic symptoms, because the recurrence of sinusitis often follows a cold that leads to an acute recurrence. The nasal symptoms mainly include nasal discharge, primarily consisting of yellow pus-like mucus. There may also be nasal congestion or a sensation of the nose being blocked, as well as headaches. The location and severity of the headache depend on which sinus is more severely inflamed, which also affects where the headache is felt. Additionally, there may be a disturbance in the sense of smell, which refers to a reduced sensitivity to smells, or a reduced ability to smell or weak sense of smell. Systemic symptoms mainly include lethargy, feelings of headache and weakness, lack of concentration, and a general lack of energy. Overall, the symptoms of recurrent sinusitis are similar to those of initial sinusitis, with most being the same.
