Headaches are quite common. Everybody gets them, albeit some are more severe than others and some can indicate something more severe. Everyone has had them - sinus and allergy headaches, migraines, etc... This article will answer the questions of what causes them and how we should treat them.
Tension and allergy related headaches. When you feel pressure in your sinus areas or if you feel pressure around the top part of your head this is what you are experiencing. They are usually a dull bothersome ache that feels like a weight hanging from that area. They also tend to slow your reactions and make you lethargic. They can last from a few hours to a few days. Allergy headaches are usually associated with sneezing, stuffy nose, and can drain from one side to the other. Treatment for these headaches is similar - acetaminophnen (ibuprofen) usually works to reduce the severity of this headache. Also, Claritin works well for alergy related symptoms. For more severe tension headaches doctors have been known to use oxygen machines and a few injectable drugs that give a more immediate effect.
Migraines. These can be quite serious and are by far the most painful. They feel like a burst blood vessel or artery as they have a pulsing feel to them. They can be so painful that they can make you sick to your stomach (nausea), cause light sensativity and even virtigo. Migraines are quite prevalent and can also indicate something more severe like a brain tumor, a weakened blood vessel, abnormal changes in blood pressure and pH, etc... Repeated patterns of migraines or other headaches should be brought to the attention of your doctor for this reason. Your body many times will tell you when something is wrong and a abnormal or irregular headache or bodyache that has become chronic is a good indication that something may be off. It may be as simple as a hormonal imbalance, new stress, etc... Regardless, your doctor knows best and it should be brought to their attention. There are over the counter products that contain pain relievers and caffeine that may work. Doctors usually prescribe beta blockers, calcium channel blockers, and other various narcotics.
