When the pain attacks, one may notice the drooping of the lids from the affected eye as well as nasal congestion on the affected side. The pain of a cluster headache is no joke. It tends to be so sever that some people say that it is nothing compared to things like childbirth or migraines. At the height of a cluster headache attack, even morphine does very little to assuage the pain. Although it is a rare cause of headache, ask neurologists to examine you for possible brain tumors. By conducting a series of tests such as CT or MRI, you can trace the possible cause of your recurrent headache. Other causes include migraine, sinusitis, fevers, glaucoma, and neuralgia. Other serious causes of headache may include meningitis, sub-arachnoid haemorrhage, stroke, blood pressure, brain tumor, and temporal arteritis. For instance, studies have proven that countless individuals complain that sinus headache cures don't work on them and this is clearly because most people who think they suffer from sinus headaches are actually suffering from migraine. This is why the headache cure they are taking do not work. Taking note and logging details about your headache attacks can help you relate and recall your headaches better for proper physician diagnosis. Symptoms of sinusitis include a sinus headache that may affect several parts of the head including the face, jaws and teeth. During a sinusitis attack, the sinus headache may be localized to one or two pairs of inflamed sinuses but in severe cases, all sinuses are swollen and therefore cause a sinus headache that can be felt in the forehead between the eyebrows, upper jaw and teeth along with tender cheeks and face, the sides of the nose. What are Headaches Statistics say that headache is one of the most common illnesses experienced by people not only in the United States but also of those who are living in different parts of the world. In fact, studies also show that a large percent of people from different places are also large consumers of different painkillers the first aid in relieving headache. There is however one kind where in the person may see a visual hallucination, called an aura, before the actual migraine headache occurs. This kind is called the classic migraine headache. The classic migraine headache is a lot different from what specialists call the common headaches, which occurs without any warning whatsoever.
