The Toon striker, 27, insists he will only listen to German surgeon Dr Ulrike Muschaweck who operated on his groin.
He said: "I'll listen to the surgeon and not anyone else because she knows what she is talking about.
"Could I play against Estonia? I don't see why not. The surgeon tells me nothing can go wrong in terms of the operation.
"I know the manager here said I did it in the last international matches but I was playing in pain even before them."
Owen scored on his Toon return in the 3-2 win over Everton on Sunday just eight days after under-going surgery in Munich.
And he added: "I've been pushing myself through a lot of pain for about six weeks - even before the last two internationals."
