Somehow I missed this post about my dads surgery. He was having headaches, dizziness, and double vision. When he went to the doctor and had his head scanned it showed that he had a cyst on his brain. They did surgery to remove it because within a few days his eye had swollen shut. It turns out there were nerves tangled up with this cyst.
Luckily all went well and he is recovering still. His vision is getting better all the time. He has been driving a few times and even rode his bike the other day. He looks normal now cause for awhile he could not control where his eye looked and it was all over the place. I am glad it's not like that anymore:)
