It's been over two months since I had the surgery and at least a month since I noticed any kind of side effects. I'd pronounce myself better. In fact I did and dyed my hair. The wound on my scalp is healed, although there is still a protruding scar and something of a divot in my head.
I've had an MRI and a CT scan recently and both of these went ok. I'll be having an appointment with the surgeon again in about 2 weeks to follow up about these. Basically it's to ensure there's no sign of the cyst and to see if my skull has begun to heal. There's a chance that it never will and that I'll have to be careful as it's only held in place by some small strips of titanium.
Hopefully it's begun to fuse up again as I'd like to get back into mountain biking and snowboarding this coming winter.
In other news I'm moving to Sydney in about 3.5 weeks.
