Did you know there is a book specifically for colloid cyst sufferers? 'How to Have a Brain Tumour' by Anne E. Thompson. It has lots of helpful advice about neurosurgeons, and headaches, and how to recover after a craniotomy (including how to get your driver's licence back!) Wish I had read it years ago. Available from an Amazon near you, US link is: https://www.amazon.com/Have-Brain-Tu...s=colloid+cyst
