Hi,
Yes, it is common to have ear aches and nasal congestion
with sinusitis. Sinusitis is usually bacterial infection and treatment is mainly
with antibiotics, decongestants, nasal sprays, humidifiers, expectorants etc. Nausea is a common side effect to use of antibiotics, but subsides with further use. Culture of discharge can determine the organism causing this infection and assistance in choice of antibiotics for this. Best.
