Sinusitis can cause long-term low fever

Sinusitis may cause low fever, but it is rare to see chronic low fever, especially in acute stage. Low fever caused by acute sinusitis is mainly due to many purulent nasal secretions in acute sinusitis. These purulent secretions will secrete toxins and stimulate the body to produce low fever response. No antipyretic treatment is needed if the body temperature does not exceed 38C5. If the body temperature exceeds 38C5, antipyretic drugs can be added as appropriate. At the same time, attention must be paid to the treatment of sinusitis to reduce the occurrence of low fever reactions. Antibiotics can be applied to the whole body. The guideline recommends cephalosporins or macrolides. When using antibiotics, nasal spray or nasal irrigation should be used to reduce the irritation of nasal purulent secretion, which can greatly reduce the occurrence of low fever. If sinusitis is cured and there is a long-term low fever, you must go to the hospital to exclude tuberculosis or other immune system diseases.
