Here's the problem that Kerr has been dealing with since his first back surgery: leaking cerebrospinal fluid (CSF). Your brain and connected spinal cord are pretty sensitive. Not sensitive in an emo type of way, but sensitive in that they can be easily damaged. Therefore, the brain and spinal cord sit in a "balloon" filled with clear fluid, called CSF, that cushions and protects these vital structures. This CSF bath helps ward off nasty microbes too. Normally the "balloon" membrane keeps the CSF from leaking out, but if this membrane is punctured, during an accident or surgery for example, then the CSF is no longer contained.
...He had suffered a ruptured disk in his back and then underwent surgery. After the surgery, he began experiencing CSF leaks, which led to another surgery later that year. The second surgery did not successfully correct the problem. Since then Kerr has gone through a wide range of attempts to ease his symptoms, ranging from different medical treatments to yoga to meditation to marijuana. To date, nothing has really worked.
...Kerr told the Washington Post, “I can tell you if you’re listening out there, stay away from back surgery. I can say that from the bottom of my heart. Rehab, rehab, rehab. Don’t let anyone get in there.”
