If your stuffy nose and cough last longer than one or two weeks, you may have more than a cold. Rhinosinusitis is a swelling of one or more of your nasal sinuses and nasal passages. It is often called sinusitis or a sinus infection. You may experience pressure around your nose – eyes or forehead, a stuffy nose, thick, discolored nasal drainage, bad-tasting post-nasal drip, cough, head congestion, ear fullness or a headache. Symptoms may also include a toothache, tiredness and, occasionally, a fever.*
