Tennis star Serena Williams is back home resting from back-to-back serious health scares. She first suffered from a developed blood clot in her lungs, known as pulmonary embolism, last week. Following her blood clot she needed treatment for hematoma. Williams spokeswoman informed People magazine that Serena received “emergency treatment” for the hematoma. The hematoma developed as a result of her more critical situation of a pulmonary embolism. Serena Williams, 29, plans to return back to the tennis court by the early summer.
