Had back surgery at Mayo two years ago. The pain from the surgery was extremely intense, and the post surgery hospital care was horrible. I ended up with significant inflamation in my brain and brain damage as a result of my back surgery. Brain damage that a Neuro at Mayo said was NOT caused by the trama of the surgery even though Mayo has a research paper stating that brain damage can occure as result of the trama from surgery. Mayo is GREAT at testing, but I would avoid having any proceedure there or getting advice on next steps after the testing.
