Murray is a UK tennis legend but he has had his fair share of problems over the years. The Scottish star won Wimbledon twice and also has a U.S. Open title to his name. But arguably, he never reached his full potential because of problems with his body. He had an ongoing hip issue that almost caused him to retire several times.
Finally, in 2018, he emerged from the depths of Hell when he had a life-changing operation. This prolonged his career by several years when he expected to quit. Murray opened up about living with pain and struggling to perform at a high level. Amazingly, he achieved what he did despite everything (via American Hip Institute).
