Normally, the sinuses produce mucus that helps keep the nasal passages moist and free of harmful particles. When the sinuses become blocked or infected, they can fill with fluid, leading to pain, pressure, and difficulty breathing through the nose. Sinusitis can be either acute (short-term) or chronic (long-lasting), depending on the duration and severity of symptoms.<\/span><\/p>\n<p data-start=\"4329\" data-end=\"4658\"><span style=\"color: #000000;\">If you experience persistent symptoms such as <strong data-start=\"4375\" data-end=\"4397\">severe facial pain<\/strong>, <strong data-start=\"4399\" data-end=\"4408\">fever<\/strong>, or <strong data-start=\"4413\" data-end=\"4438\">persistent congestion<\/strong> lasting more than 10 days, or if you have frequent sinus infections, it\u2019s important to see a healthcare provider.
