hi, i was treated years back for an arachnoidal spce cyst, or os the dr said. But the headaches i had before have continued since. I get this pressure in the skull as if the brain has increased in size; other times as if the brain is being boiled in water and then also sometimes as if stabbed repeatedly in the skull. these heaaches also activate from atomspheric pressure changes, like an approaching storm front or sudden altitude changes.
could the cyst have returned? anyone please help...feel like i am going mad here
