PinkGrandma, I had my chemoembolization done last March, so nearly a year ago. I've never had encephalopathy. I did have quite a bit of pain following the chemoembolization, and for several weeks I slept 20 hours out of 24. I also had a new treatment, Theraphere, about a month after the chemoembolization. I was #2 in a study at Mayo involving Therasphere.
