Symptoms can include a headache, painful face in the area of the sinuses, a stuffy nose, achy teeth, postnasal drip, cough, sore throat, laryngitis
, constant low fever, and thick, yellow to green
nasal drainage. This can certainly cause you to feel lethargic, drowsy, and just achy. A CT scan of the sinuses easily identifies this problem. If your symptoms are due to sinusitis, this will last as long as the inflammation continues.
