Dani Pedrosa believes it will take several MotoGP races to find out if surgery has finally solved his arm pump problems.

The Repsol Honda star withdrew from competition after the cramp-like symptoms, for which he had twice previously gone under the knife, flared up again in the Qatar season-opener.

As a result, the April 3 operation saw doctors completely removed the layer of fascia around the muscle of his right forearm. After missing three events, Pedrosa will return at this weekend's Le Mans round.

"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," he said at Le Mans 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 made the decision to seek further medical advice after non-surgery techniques had failed.

"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."

The Spaniard added that he hadn't seen the recent races on TV because he finds it hard to watch when he should be riding.
