NEW YORK  — Serena Williams is back home recuperating after two health scares she describes as "extremely hard, scary, and disappointing."

Her agents confirmed Wednesday that Williams suffered from a blood clot in her lungs last week and later needed treatment for a hematoma.

"I know I will be OK, but am praying and hoping this will all be behind me soon," Williams said in a statement. "While I can’t make any promises now on my return, I hope to be back by early summer. That said, my main goal is to make sure I get there safely."

Spokeswoman Nicole Chabot told People magazine that Williams underwent "emergency treatment" Monday for a hematoma suffered as a result of treatment for "a more critical situation," a pulmonary embolism.

The 29-year-old Williams was treated at a Los Angeles hospital.
