সাধারণ মাথাব্যথা না কি গুরুতর কিছু: কখন সতর্ক হবেন?

Almost everyone gets headaches, and the vast majority are harmless — caused by stress, tiredness, dehydration or migraine. Only a small minority signal something serious. Knowing the difference brings peace of mind.

Usually not dangerous

Tension headaches and migraines that come and go and respond to rest or usual medicine.

Red-flag symptoms — see a doctor promptly

• A new, severe headache unlike any before ("the worst headache of my life")
• Headache that steadily worsens over days or weeks
• Headache with vomiting, blurred or double vision, or seizures
• Headache with weakness, numbness, or difficulty speaking
• Early-morning headaches that wake you from sleep

These do not automatically mean a tumor — but they are worth checking, sometimes with a brain scan.
