Thank you for posting your query.
There are two common reasons for hiccups after head injury:
(low sodium level in blood)- this can be confirmed by a blood test
. Giving additional salt in the diet can correct it.
2. Injury to the brainstem- this is less likely, as there are no other symptoms (such as weakness of hands and legs, imbalance while walking, slurred speech, difficulty in swallowing, etc). If still in doubt, MRI
scan of brain can help.
