The Liverpool striker’s stop-start season was cut short earlier this month when doctors in the United States decided to operate on the damage.
But the frustration of making just 18 appearances in all competitions is lifting, according to a message posted on the 25-year-old England international’s social media.
Sturridge tweeted: “Two weeks post op and I’m feeling a lot better. I’m a happy man today.”
Brendan Rodgers said recently he hoped a long-term solution to Sturridge’s injury problems had been found.
“I think we have found some underlying issues that maybe relate to Daniel’s issues and problems this season and the ongoing problems he’s had,” the Liverpool manager said.
“The medical team here, liaising with some of the medics in America, are doing everything we possibly can to give Daniel every opportunity to stay consistently fit and available.”
