Been BACK in hospital (29th October 2012 - 17th December 2912)... They found out I had an infection under my bone plate apparently its rare to have one nearly a year on...had my bone plate removed and 6 weeks of intensive IV antibiotics....got to have a metal plate put back in hopefully May/June this year ...so spent my 1 year anniversary of me collapsing in hospital which could have done without like a hole in the head (pardon the pun) lol
Don't want to scare you, but it is my opinion that can be very dangerous. I'm only basing it on one personal friend's experience. He had a benign brain tumor, which was successfully removed. He never recovered well, and they finally determined he had gotten a staff infection. He's been fighting that almost two years now, with a lot of side effect, not from the tumor, but from the associated infection.
I would encourage you to have your medical team follow that very closely.
