This happens to my Mom sometimes. When she's really stressed, tired, sick, etc; her immune system starts attacking her body again. I don't know why, it just does. It happened with her immune system or something like that and also her eyes. The immune System needs to know what is friendly and a threat to the brain & body. Although it has trouble sometimes when you get a transplant and the shape/size/composition/etc isn't similar enough to your own.
