Thanks for posting,
Your daughter's problem is delicate and if there is a cyst
in his brain, then that is the cause of all of this. The cyst has to be monitored for progress and if it is actually the cause for the migraine
, then normal pain killers would not help (i am afraid). What she might need as definitive treatment is a brain surgery
. You will need to see a neurosurgeon for this problem. Other specialist will only try to treat the symptom, but a neurosurgeon might definitely go for a brain surgery (which can be done with about 90% success rate).
Hope this helps
