BERLIN (AP) — The German hospital treating Yulia Tymoshenko says the former Ukrainian prime minister is in significantly less pain after nearly a week of treatment for three slipped discs she suffered while imprisoned.

Berlin’s Charite hospital said in a statement Friday that Tymoshenko is very satisfied with the outcome so far of what it called “conservative” treatment. It isn’t yet clear whether the 53-year-old will require an operation; the hospital said a decision will be made in the coming days.
