MOSCOW (AP) — A jailed member of the Pussy Riot feminist punk band has been hospitalized for a full medical check-up after complaining of headaches and suffering from overwork at a prison colony known for its tough conditions, her lawyer and a fellow band member said Friday.

Nadezhda Tolokonnikova has suffered from headaches since last spring and her condition has worsened since October when she was sent to a prison colony to serve her two-year sentence for the band's irreverent protest against President Vladimir Putin in Moscow's main cathedral, her lawyer Irina Khrunova said.

She sent a request to prison authorities in December to admit Tolokonnikova in order to perform a detailed medical check, and she was hospitalized on Jan. 24, the lawyer said.

Yekaterina Samutsevich, a band member who also was sentenced to two years in August but later released on appeal, added that Tolokonnikova feels exhausted after working long hours with little sleep.

"They don't allow her to have any rest; she works nearly round the clock," Samutsevich told independent Rain TV on Friday. "She said she feels tired, extremely tired."
