Hi,
Thank you for posting your query.
One of the possibilities could be worsening of
hydrocephalus. This can be confirmed with a
CT scan of the brain. In case, there is hydrocephalus, you may require shunt surgery.
If you had
migraine earlier, the current headache could be an exacerbation of the same.
I hope my answer helps. Please get back if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
