Head Ache :
A headache is a general condition that refers to the pain or discomfort felt in the head, scalp, or neck. A headache can vary from mild to severe type and sometimes even feels like a dull ache, throbs, or even a sharp pressure. Primary headaches are conditions such as tension headaches, and secondary headaches are caused by underlying conditions like sinus infections, dehydration or stress, among others. Depending on what type of headache it is, the symptoms can be different. For example, a tension headache may create band-like pressure around the head. Sometimes, it causes throbbing pains, nausea, and sensitivity to light or sound. Usually, a physical examination and medical history help the doctor to get to the diagnosis. For cases with more serious conditions, the doctor may prescribe an MRI or a CT scan. Treatment depends on the cause. Minor headaches can always be treated with over-the-counter pain medicines like ibuprofen and acetaminophen, but many are moderate and need prescription medicines. Preventive measures include drinking water, managing stress, and maintaining regular sleep patterns.
