It has been reported that some patients have been misdiagnosed with Rhinitis, when in fact the correct diagnosis in their specific case was Sinusitis.
Sinusitis occurs when the spaces filled with air in your nose and head are swollen and inflamed. It stops the mucus in your nose from draining properly making your nose feel stuffy and makes breathing difficult. Symptoms of sinusitis include thick discoloured discharge from the nose, post nasal drainage down the back of the throat, blocked nose, pain, tenderness and swelling around the eye, cheeks, nose and forehead, reduced sense of smell and taste, cough, sore throat, fatigue, ear pain and headache. Sinusitis can be misdiagnosed as cavernous sinus thrombosis, brain abscess, meningitis, orbital cellulitis, mucormycosis, dental infections and brain tumours.
