Sudden severe headaches can be alarming and should never be ignored. While headaches often arise from common causes like stress or lack of sleep, sometimes they may signal serious health issues.

• Stress, anxiety, and fatigue: Modern lifestyle factors like stress, dehydration, or lack of sleep can trigger headaches. Migraines often cause severe pain on one side of the head, sometimes accompanied by nausea, vomiting, and sensitivity to light or sound.

• Digestive issues: Gas buildup, constipation, or acidity can also lead to severe headaches.

• Infections and fever: Viral infections like flu or cold may cause headaches. If headaches are accompanied by fever and stiff neck, it might indicate a dangerous brain infection requiring urgent medical care.

• High blood pressure: Extremely high blood pressure can cause a severe headache, usually felt at the back of the head.

• Medication or caffeine withdrawal: Suddenly stopping painkillers or caffeine intake after long-term use can also cause intense headaches.

• Serious neurological conditions: Brain tumors, stroke, or other serious brain conditions may present with continuous severe headache along with vomiting, weakness, or difficulties in speaking or seeing.

• Rest in a quiet, dim environment

• Drink plenty of water to avoid dehydration

• Gentle massage of temples, neck, or head to ease muscle tension

• Moderate caffeine intake (a cup of tea or coffee) may help but avoid excess

• Ensure adequate sleep

• Home remedy: Basil-ginger decoction is known to provide relief

Seek urgent medical attention if:

• The headache is sudden, intense, and unlike any before

• Headache is accompanied by fever, stiff neck, vomiting, fainting, weakness, or difficulty speaking or seeing

• Seizures occur along with headache

• Headaches persist for more than a week or occur frequently

Ignoring severe headaches or delaying treatment can lead to serious complications. Always consult a healthcare professional if you experience any alarming symptoms.
