I would give up all the perfect comforters in the universe if it meant that my loved ones didn't have to suffer.
My poor little niece Bug, who already endured an open heart surgery last year (and a small surgical procedure a few months before that), had some massive migraines after her heart surgery. They went away shortly thereafter, but not before her doctor scheduled a MRI to be on the safe side. The MRI found what is called a Chiari Malformation I. Basically it means her skull is too small for her brain and that her brain is being squeezed through the foramen at the bottom of her skull. It wasn't putting any pressure on her spine, so they just scheduled an MRI in a year to keep an eye on it.
The second MRI was Friday and the results came in today. It is now putting pressure on her spine and causing some other issues. So, another MRI is scheduled in a year and in the meantime her parents have to be on the lookout for any symptoms (dizziness, motor-function issues, headaches, etc) in case it gets worse before the next check-up. This all means that there are higher-than-average odds that Bug will need to have brain surgery in the next year.
NOT. A. FAN.
