After surviving a serious medical emergency last week, Serena Williams headed to a Beverly Hills doctor's office to check her progress on Wednesday afternoon (March 9).
A fearless competitor on the court, the 29-year-old admits she was terrified by the Pulmonary embolism and hematoma found in her lungs just days ago.
The former world number one said doctors told her that she most likely developed the life-threatening clots because of complications from surgery to repair a foot injury and the effects of constant flying, a regular hazard for all professional tennis players.
The hematoma was successfully removed by surgery and the 13-time Grand Slam singles champion is currently taking blood thinner medication while hoping to be back on the court again soon. She told, "I like having a challenge, and this will be my biggest challenge yet."
