"It is so refreshing because basically all of last year, in the grand slams and a couple of other tournaments, I was playing with pain-killers before every single match," Sharapova told reporters on Wednesday.
"Even though during the match it might be taking care of the pain, you know at the back of your mind it's not 100 percent and you have to do something about it.
"For much of last year, I couldn't serve and I couldn't hit a backhand volley so I couldn't work on either of those."
