My 6 year old son had decompression surgery Dec 28th 2011. We just got his stitches removed today. He has done fairly well so far. My only concern right now is that he can not straighten his head. His chin is downward and his head is tilted to the left. It is very noticeable, and makes it hard for him to balance. Dr said that this is not due to the surgery. He was able to move fine before. We go back in 3 weeks.....Why is it like this?
