The pain of a sinus headache often feels like pressure or fullness in the cheeks or forehead, according to Mayo Clinic. The pain often feels worse when bending over or lying down and may come with fatigue, nasal congestion and aching in the upper teeth.
The pain of a sinus headache corresponds to the locations of the sinuses, which are in the forehead, cheekbones and the bridge of the nose, notes WebMD. Sinus headaches cause deep and constant pain in these areas. The symptoms of a sinus headache often appear with other sinus problems, including a runny nose, fever, swelling in the face and a full sensation in the ears.
The symptoms of a sinus headache sometimes mimic those of a migraine, states Mayo Clinic. Like a sinus headache, migraine pain often increases when leaning over and may include nasal symptoms. One main difference is the lack of nausea and vomiting with sinus headaches. Another symptom that typically applies to migraines but not sinus headaches is sensitivity to light and noise.
A sinus headache typically occurs after a cold or upper respiratory infection, as Mayo Clinic explains. Other signs that point to a sinus infection over a migraine include a decrease in the sense of smell and a thick nasal mucus in contrast to the clear, watery discharge associated with migraines.
