The news emerged as the seven-time Formula One champ continues his "long and difficult road" to recovery following his skiing at the end of 2013.
An article in Italian newspaper Corriere della Serra explains that despite the sad news of his pain, it is "valuable" to know that he is making some sort of contact with his loved ones.
Writer Giorgio Terruzi pens: "Schumi cries. And sometimes mysteriously. He cries when he hears his children, his wife's voice, his dogs. In the silence of that room, a tear runs down his thin face at a known sound.
"We have a man that we usually consider unbeatable...engaged in a struggle."
He adds: "Inside this we can find... There is life, enclosed in a drop; there is the strength of a man who is moved and that moves each of us. We have his tears, his senses exposed."

The former driver awoke from his coma six months ago but doctors have not commented on any significant improvements to his health.
His friends and family today marked the occasion by wishing him well in his fight.
His old team Ferrari sent a touching tribute to their champion, saying: "A year ago, just a few days after the skiing accident in Meribel, a group of Prancing Horse fans had unfurled the giant Ferrari Heart banner outside the Grenoble hospital, in a gesture of support.
"This year, Michael will spend his birthday at home, surrounded by those close to him, as he daily continues his rehabilitation. Everyone at Ferrari and his many fans around the world send all their best wishes and, as always, Forza Michael!"
