Got Epudiral 2 Years Ago Couple Months After Started Having

Got epudiral 2 years ago couple months after started having headaches got ctscan came back find had eeg and sleep study and everything fine doc said migranes. No medication helps also where epudiral was is very sensitive and if touched feels like pressure. My head hurts almost everyday. Sometimes dizzy my regular doc is sending me to eye doctor to check if it's something about my eyes that makes you think you have tumor but don't but I was thinking could it be a brain fluid leak?
