Thank you all for your comments in various places about the potentially moving bone flap from my surgery (here, Tumblr, etc.).
My neurologist, physician, and neurosurgeon all think that it's not moving, and seems okay, which puts my mind to ease a bit more, though I'm a little antsy about now even being able to SEE the bumps on my forehead from the clips instead of just being able to feel them.
But... As long as they aren't moving!
And also, I may have Ehlers-Danlos Syndrome, along with my mother, apparently.
The specifics are in my blog entry, since I don't have time to type it out, but apparently it is linked to AVMs. It will be interesting to see what the results will be when I get tested!
