Murray, due to face France's Benoit Paire in the first round, was out on the All England Club practice courts on Saturday and insisted he was generally pleased with his return to action.
But with just three matches under his belt since returning from almost 12 months on the sidelines he enters his home Grand Slam in a different mindset to any of his previous appearances at SW19.
"I need to be very open with my team about that and let them know exactly how I'm feeling, which maybe in the past, sometimes things are a bit sore, you just kind of get on with it, whereas now I need to be smart with that".
'He just came back, and I have a lot of confidence, but it will be, for sure, a tough match.
"I've always loved that and enjoyed that in a way. It has been hard but I enjoyed it, whereas this year it feels very, very different".

Andy Murray is returning to Grand Slam scene after spending 11 months on sidelines recovering from hip surgery.
"Through all of this, I have to view it very much day by day, just as a process". "I'd like to be playing better", he said.
"These things are significantly better than what they were a few months ago". Two weeks ago I practised with Kyle and I didn't win a game. "I think that's helped me quite a bit". I would expect my level of tennis to improve.
"That's really positive for me as part of getting better, to compete again", said the Scot.
Murray's reward for victory over Paire would be a likely second-round meeting with Denis Shapovalov, while Juan Martin Del Potro could prove a testing third-round clash.
Despite being "pumped" to be back Murray admits he will only know exactly how good his condition is after playing a best-of-five-set match.
The 32 year-old Scotsman continues to evaluate his physical fitness on a daily basis, and is practicing again today in preparation for the match on Tuesday. "I can't answer that question honestly", he said.
