Agafya Lykova, 71, airlifted to hospital after suffering 'acute pains' in intense cold at her forest home more than 100 km from nearest town.
The reclusive hermit was rushed to Tashtagol hospital in Kemerovo region on the personal orders of the governor of Kemerovo region, Aman Tuleyev.
Clasping her icons and spring water, the devout Old Believer was flown for treatment after getting a message to the outside world that she was in pain in her legs, restricting her movements.
Previously Agafya has refused to be flown out of the forest home built by her parents - where she was born - after they opted out of the Stalinist USSR claiming religious persecution.
A source said: 'Now Lykova feels better. Doctors removed the acute pain. It is planned that she will stay at the hospital for examination and treatment for a week.'
Her family fled into the wilderness in 1936 and when they were discovered living off the land after being spotted from the air in the 1970s, they had no idea World War Two had started - or ended.
Today she admits that the extreme winter cold on her lonely farmstead is 'unbearable' - with temperatures sinking to minus 40C - but she has repeatedly refused offers to live in a village or town where she could be helped.
Recently she has been bothered by wild bears and foxes seeking food. Despite this she is expected to ask to go back to the only home she has ever known - seen here in our pictures.
Her little plot is located close to a river about some 150 metres up a remote mountain side in the Abakan Range, in south-western Siberia. She was the fourth child of Karp and Akulina Lykov and for the first 35 years of her life she had no contact at all with anyone outside her family.
It was in the summer of 1978 that a group of geologists accidentally stumbled across the family, with scientists reporting that Agafya spoke a strange blurred language 'distorted by a lifetime of isolation'.
Her father had taken the decision to flee normal civilisation in 1936 after a communist patrol arrived at the fields on which he was working and shot dead his brother.
