about 21, woke up with a huge pain in the back of my head, paniced, called doctor...
was incidental at first, but it got worse and worse, spend 7 years wandering what itw as, no doctor could tell me, had therapy, nose operation, the usual.
kinda figured it out myself, after some research.
now chronic, but not too bad, exept a couple times a year, when im a mess for months.
