Recently studies have shown that approximately 45 million people in the United States alone have reported having headaches for which they have to take some type of pain medication. While the majority of the headaches suffered are not serious in nature, they can be at least temporarily debilitating. Headache pain can be caused by many different things. Some people get tension headaches from the stress they suffer when dealing with every day life activities involving family and work. Some people suffer from headaches due to medical conditions such as migraines, sinus problems, and allergies.
