The sinuses
Sinuses are air-filled cavities (spaces) located in your forehead,
cheekbones, and behind the bridge of your nose. The sinuses produce a thin mucus
that drains out of the channels of the nose. When a sinus becomes inflamed,
usually as the result of an allergic reaction, a tumor, or an infection, the
inflammation will prevent the outflow of mucus and cause a pain similar to that
of a headache.
What are the symptoms of sinus headaches?
Sinus headaches are associated with a deep and constant pain in the
cheekbones, forehead, or bridge of the nose. The pain usually intensifies with
sudden head movement or straining. The pain is usually accompanied by other
sinus symptoms, such as nasal discharge, feeling of fullness in the ears, fever,
and facial swelling.
Whether the symptoms of headache can actually be attributed to the sinuses
will need to be determined by a physician. If your headache is truly caused by a
sinus blockage, such as an infection, you will likely have a fever. CT scans or MRI, along with a physical examination, are usually conducted to
determine if there is a blockage in your sinuses.
How are sinus headaches treated?
Treatment of sinus headaches is usually directed toward symptom relief and
treating the infection. Treatment might include antibiotics for the infection,
as well as a short period of antihistamines or decongestants to treat the
symptoms. If you take decongestants but do not have a true sinus headache, the
medication could make your headache worse.
Other medications to treat sinus infections include analgesics
(pain-relieving medications) and vasoconstrictors. Corticosteroids may be
prescribed for some people when the pain continues after the use of analgesics.
When an allergen is causing the sinus flare-ups, preventive allergy therapy is
often needed.
Decongestant medications can be used to relieve headaches associated with
sinus infections. Decongestants help relieve headache symptoms because they
constrict blood vessels that cause headache pain. However, decongestant use can
be habit-forming. If your headaches seem to be relieved by decongestants but you
do not have a sinus infection, you may actually have a migraine or tension-type
headache, which require treatment with abortive or preventive medications.
For treatment of chronic sinusitis, warm moist air may alleviate sinus
congestion. Using a vaporizer or inhaling steam from a pan of boiling water
(removed from heat) may also help. Warm compresses are useful to relieve pain in
the nose and sinuses. Saline nose drops are also safe for home use.
Allergy and headache
It is a misconception that allergies cause headaches. However, allergies can
cause sinus congestion, which can lead to headache pain. If you have allergies,
the treatment for your allergy will not relieve your headache pain. The two
conditions generally must be treated separately.
