Can Sinus Infections Cause Bad Headaches for 3 Weeks?

Headaches can range from minor tension headaches originating in the temples to full-blown migraines that require doctor's care and medication. Most headaches can be eased with over-the-counter pain relievers, and they can be kept away by avoiding the cause.

Headaches due to sinus infections can linger for weeks, although 10 days is the average. If your headache is caused by a cold or allergies, it will probably last as long as the virus or exposure to the allergy, but it is imperative to seek medical attention even after just a few days to find out if is caused by an infection that needs to be treated with antibiotics.

  1. Identifying a Headache Caused By Sinus Infection

    • A sinus headache is not always easy to identify. Generally, the pain will originate in the sinus cavities of the face. A common area for the pain is between the cheekbone and the nose; however, the pain from a sinus infection often feels like a toothache. Green or yellow mucus is another indicator of infection. Have a doctor look at it right away to determine the best form of treatment including relief of the headache.

    Sinus Infection vs. Sinus Headache

    • Sinuses are easily irritated by dry air, allergens or viruses, and these irritations can lead to infections. A headache caused by irritation of the sinuses is commonly above or behind the eyes and will last as long as the irritant is present. A sinus infection won't clear up on its own and must be treated by a doctor. The headache can be present as long as the infection is active.

    Antibiotics

    • Your doctor will most likely prescribe antibiotics, and you will probably begin to feel some results in a few days. As the infection decreases, the headache should ease, but the length of time you'll have the headache depends on the severity of the infection. As long as there is still pressure in the sinuses, you'll most likely still have a headache.

    Pain Relievers

    • Although a pain reliever will not reduce the length of time that you have a headache, it will make it more bearable. Most doctors recommend an over-the-counter remedy such as ibuprofen or naproxen, but don't take them longer than the recommended time in the directions.

    Nasal Sprays

    • While they can't cure a sinus infection or get rid of a headache, over-the-counter nasal sprays will lubricate sinuses and give some relief. However, they shouldn't be used more than a few days or they could have the opposite effect. Your doctor can prescribe a nasal spray that can be used for longer periods of time if your infection and headache persist.
