Millie, first off, oxycontin in small doses never affected Frank mentally except for making him happier. last year we were faced with tumor close to carotid, doc said if we can`t do surgery, he`d be dead in a couple months. He had the surgery, and they handled it by tying his carotid artery off below the tumor. Understand, they need to do tests to see that the other carotid provides enough blood flow to the brain..............i`d get a second opinion........Dee
