Waking up with a headache every morning may be caused by poor sleep quality, sleep apnoea (brief pauses in breathing during sleep), teeth grinding during sleep, sinus problems, dehydration, stress, or poor neck posture. A low blood pressure reading of 100/60 is usually not dangerous in many people, but in some, it may contribute to tiredness or mild dizziness rather than persistent headaches. Vertin (Betahistine) is primarily used to treat vertigo (dizziness) and balance-related disorders and is not usually prescribed for headache itself. Zerodol SP (Aceclofenac, Paracetamol, and Serratiopeptidase) is a combination pain-relief and anti-inflammatory medicine that may help reduce headache temporarily, but it does not treat the underlying cause. If your headaches occur daily, it is important to identify the root cause rather than just controlling the pain. You may need further evaluation, such as a sleep assessment, eye check, sinus examination, or review of stress and lifestyle factors. If symptoms persist or worsen, follow up with your doctor for a more detailed assessment and appropriate long-term treatment plan.
