Does sinusitis cause fever?

A raised temperature can occur with sinus inflammation and may come with congestion, facial discomfort, tiredness, or thick nasal mucus. Fever also has many other causes, including viral illnesses elsewhere in the body, so it does not identify sinusitis on its own. Pay attention to how you feel overall, whether symptoms are improving or worsening, and whether new signs such as eye swelling or breathing difficulty appear.

Rest, drink fluids, and wear light clothing if you feel overheated. Check your temperature using a thermometer and keep a note of associated symptoms. A pharmacist or clinician can advise on fever relief that is compatible with your age, medicines, pregnancy status, and medical conditions. Do not combine products that contain the same pain-relieving ingredient, and do not use antibiotics left from an earlier illness.

Seek prompt medical advice for a fever that is persistent, worsening, or accompanied by severe facial pain, swelling around an eye, or a very unwell feeling. Get urgent help for confusion, neck stiffness, trouble breathing, dehydration, or a severe headache. Children, older adults, pregnant people, and anyone with a weakened immune system may need earlier advice.
