Sinus headaches is a common term used by patients and some healthcare providers to describe pain or pressure in the face, over the cheeks or forehead, or between or behind the eyes.
Thick yellow-green drainage from the nose
Sinusitis in children can look different than sinusitis in adults. Children tend to have a cough, bad breath, low energy, and swelling around the eyes, along with a thick yellow-green post-nasal drip.
Sinusitis, also called rhinosinusitis because the symptoms involve both the nose and the sinuses, affects about one in eight adults annually.
