WWE legend Hulk Hogan passed away last month at the age of 71 at his home, where he had lived with his wife, Linda, also known as Sky Daily. Since Hulkster's demise, numerous conspiracy theories have circulated on the internet questioning the cause of his death. Later, a report suggested that medical malpractice may have partially led to Hogan's death, as confirmed by his own wife, Sky.Now, the Daily Mail and TMZ, in an exclusive report, have revealed that Sky Daily has been "planning" to file a medical malpractice lawsuit regarding the neck surgery Hulk Hogan underwent in May.She believes that surgery "compromised" the legend's phrenic nerve, which controls breathing. This may have contributed to the Hall of Famer's sudden passing, despite him being in good health."We are investigating for possible malpractice. If you have shortness of breath for a long time, that makes you very sick. 'It's not something that's an alarming (sudden) cause of death. It's something that wears on you, makes you weak," Sky said.
