Pedrosa underwent surgery on April 3 after complaining of cramp-like symptoms following the season-opening race in Qatar, in which he finished sixth.
The Spaniard, who has gone under the knife twice in the past for the same problem, missed the last three MotoGP races in USA, Argentina and Spain, and he is hoping to have a successful comeback at the Grand Prix de France in Le Mans on Sunday.
"The doctor after the surgery told me that he was happy with how the surgery went and he could see that there was some issues there, but obviously I won't know exactly [how the arm is] until I ride the bike again," Pedrosa told reporters on Thursday. "I think that it's going to be a few races before I know how the situation is.
"The first race I might not be in the perfect condition for riding, so I don't think tomorrow or Sunday will be the perfect scenario to know [if the problem has been solved] and it might take a few races to know."
Pedrosa also revealed that he opted to take the surgical route after physical therapy had not solved the problem.
"I was riding last year in difficult conditions and I was trying to do all the therapy to try and improve, but after Qatar I knew that it wasn't the way that I could ride," he said. "It was so demanding mentally because I knew that I could do better and at the end I needed to choose between finding a solution [surgery] and deciding to race on."
