Sinus pain in the back of the head can be treated by breathing moist air, taking over-the-counter pain relievers and decongestants, and alternating hot and cold compresses over the sinuses, according to the American Academy of Otolaryngology. For the most effective relief, these methods should be used together.
Sinusitis caused by an inability to drain mucus from the sinus cavities due to environmental factors or illness typically causes sinus pain in the back of the head, as the Penn State Milton S. Hershey Medical Center indicates. For the most effective treatment of sinus pain, the underlying condition must be identified, states the University of Maryland Medical Center. Sinusitis due to allergies should be treated with antihistamines, whereas sinus pain that is not related to allergies and lasts longer than a week may require antibiotics.
Certain treatments and lifestyle changes can treat sinus pain, regardless of the location in the skull or the underlying cause, as the University of Maryland Medical Center suggests. Over-the-counter pain relievers such as aspirin, acetaminophen and ibuprofen help reduce sinus swelling while reducing pain. Cool-mist humidifiers, breathing in steam two to four times daily (such as in a hot shower or steam room) and nasal sprays may loosen congestion in the sinuses. Treating the underlying cause while using these therapies is recommended for maximum relief.
