The former Tottenham star sustained a groin injury against Vancouver Whitecaps on April 4 and although he admits he cannot stand being on the sidelines, he is dealing with the scenario a lot better than he once would have.
"I love playing, so it's been a bit frustrating, but it's just the way it is," said Keane.
"If it had happened a few years ago, I probably would have been an absolute disaster in the training room, because I'm the worst person in the world to be injured.
"But as you get experience, you [learn to] make sure you look after yourself well, and of course I want to get back as quick as I can, and I'm certainly on the mend, but I just have to be very, very careful that it doesn't come back again."
2014's MLS MVP has managed just four appearances for the Galaxy this term, scoring two goals, as last season's premiers sit sixth on the Western Conference table in his absence.
