Rafael Nadal enters Wimbledon on good footing after procedure to relieve pain

LONDON — Rafael Nadal on Saturday said the procedure he had on his chronic foot injury after Roland Garros has meant he is largely pain-free, but he is unsure how long the treatment will be effective.

«The feeling and overall feelings are positive, no, because I am in a positive way in terms of pain, and that's the main thing,» Nadal said.

Nadal has been suffering with Muller-Weiss syndrome, a rare condition which causes chronic pain in his left foot. He numbed the injury at Roland Garros by injecting the nerve to allow him to play.

The injury causes him to be in pain when walking, let alone playing. After Roland Garros, Nadal underwent a radiofrequency nerve ablation, which targets the specific nerve leading to the painful area of his foot.

At the time, Nadal said the success of that procedure would dictate whether he was going to play at Wimbledon, as he was not willing to again undergo daily injections. If the procedure didn't work, Nadal said he then would have either required major surgery or would have looked to alternative solutions or outcomes.

However, it has proven effective enough to allow Nadal to continue his charge for a calendar Grand Slam, having already taken the Australian and French Open titles this year.

«Well, is obvious that if I am here, it's because things are going better. If not, I would not be here,» Nadal said. «So quite happy about the things, how evolved. I can't be super happy because I don't know what can happen.

»First of all, I can walk normal most of the days, almost every single day. That's for me the main issue. When I wake up, I don't have this pain that I was having for the last year and a half, so quite happy about that. And second thing, practicing. I have been in overall better,
