In case of acute sinusitis chances are your sinuses may drain naturally over a period of time, albeit some discomfort and congestion. In case of recurring or chronic sinusitis, you will have frequent episodes of sinusitis which will not just cause discomfort but lead to loss of quality of life. Though sinusitis itself is benign in nature, prolonged episodes of sinusitis may lead to spread of infection to other areas causing serious issues such as brain abscess, meningitis or bone infections. Always consult a Sinus Specialist if your problem persists or recurs.
