Hi Mr Vijay,
Thank you for posting your query.
The most likely cause of your headaches is migraine. In migraine, one has repeated episodes of headache, which is often one-sided. In addition, feeling of nausea or vomiting may be present. There may be increased sensitivity to bright light and noise.
There are good medicines available for treating migraine such as beta blockers, flunarizine
, botulinum toxin, etc.
Other possibility is cluster headache
, which also can be treated with good medications.
Since your MRI scan of brain is normal, there is no need to worry.
Please consult a good neurologist
at Delhi (such as Dr Vinit Suri at Apollo Delhi, Dr Puneet Aggarwal at Max, Saket, etc).
Wishing you good health,
Dr Sudhir Kumar MD DM (Neurology)
