Fourth seed Agnieszka Radwanska allayed any concerns over the leg problem that required attention at the Australian Open on Friday, insisting pain is her second name.
Radwanska needed treatment on her left leg on three occasions en route to a comfortable 6-4 6-0 third-round win over Monica Puig at Melbourne Park.
The 2014 Australian Open semi-finalist, who withdrew from the Sydney International due to the same problem, required extra strapping to her lower leg at the start of the second set before the trainer was requested again in the third and fifth games.
However, Radwanska said the pain is nothing new to her.
"A lot of running, a lot of tennis these last couple of weeks. That's why I can feel it but I can still play my best tennis, which is a good thing," Radwanska told Channel Seven afterwards.
"I think pain is my second name. I'm kind of use to it. Pills are not working, tape is not working, so just have to deal with it."
Of the match itself on Margaret Court Arena, Radwanska, who won the final nine games, added: "I was in big trouble in the first set, but I found my rhythm.
"It was another great match. I just hope I can keep it up."
German Anna-Lena Friedsam is next up for Radwanska in the round of 16.
