The tennis superstar posed with Judy Murray on his social media account, saying: “Best way to feel better after a tough day is a big cuddle from your mum.”
It came after he announced his career will end after Wimbledon this year – and possibly even sooner than that.
“Genuinely been very touched by all of the messages and support from everybody today… It means a lot and has made me feel much more positive than when I woke this morning. Thank you so much,” he said.
Injury may mean Murray will be prevented from playing beyond the Australian Open next week.
The 31-year-old Briton played only 12 matches last year and, returning to the Brisbane International last week, he won his opening match but lost in the second round, visibly limping at times.
He said he plans to play his opening match at the Australian Open on Monday against world number 22 Roberto Bautista Agut.
However, when asked if this might be his last tournament, he said: “Yes I think there’s a chance of that for sure because I’m not sure I’m able to play through the pain for another four or five months.”
Murray wiped away tears during a 10-minute press conference and at one point was so overcome by emotion that he walked out.
Scotland First Minister Nicola Sturgeon led praise for the double Olympic champion after he made his announcement.
