Introduction:
Headaches are a common complaint, but not all are harmless. Some headaches may signal an underlying neurological condition, including brain tumors or vascular issues.

Red Flag Symptoms (Seek immediate care):

• Sudden, severe “thunderclap” headache

• Headaches with nausea, vomiting, or seizures

• Persistent headache that worsens over time

• Headaches with vision problems or speech difficulty

• Headache with neck stiffness or fever

Primary vs. Secondary Headaches:

• Primary: Migraines, tension headaches—generally not dangerous

• Secondary: Caused by underlying diseases like tumors, meningitis, or hemorrhage

Conclusion:
While most headaches are benign, persistent or unusual symptoms warrant medical attention. Early evaluation by a neurologist or neurosurgeon can rule out serious causes like brain tumors or hemorrhages.
