Emotional stress, fatigue and depression can trigger a tension headache. Nausea, vomiting and sensitivity to light are common migraine symptoms. The cause of migraines is still a mystery to researchers. Like migraines, cluster headaches occur on one side of the head. The intense stabbing pain is usually located around the eye, which may cause the eye to water.
Cluster headaches can also cause a blocked or runny nose.
Sinus headaches are usually caused by a cold or sinus infection. Sinus decongestants can provide relief for sinus headaches. And, effective medications may be prescribed to people who are prone to headaches. More than half of the 16 million Americans who suffer from headaches have never been diagnosed. If you experience chronic headaches, call your physician.
