dear patient ,as described your situation of headache your CT and MRI
are normal means none of problem like injury
, clot, etc. so it is mostly a type of migraine
. i know you have taken many type of treatment but not found permanent response as need. but don't be worried about it. if have you constipation
so cured it first .and stop acidic food, junk food more spices. sleep regular , dont more work of brain at evening, this advice can help you to control your pain. and for permanent cure you can send your more information like family history , weight, how many monthly attacks?
