The Dutchman missed Saturday's victory over Chelsea because of the problem but insists he is ready to return at the KC Stadium.
"I am good again now and am ready to go if I am selected of course," he said.
"They would not take any risk for the Chelsea game, I was in that much pain it was too much of a risk to play."
In his absence fellow summer signing Marc Muniesa filled in despite primarily being a centre-back and Pieters is not taking re-selection for granted.
"Marc did really well and I am very proud of him. We came to Stoke together and I know it was difficult for him because he didn't play many matches," he told stokecityfc.com.
"But when he played against Chelsea it was good for him and good for the team.
"I want to play as well, but if the manager chooses from me or Marc, it is no problem."
