Sai Ram. As He keeps telling, all of us are incarnations of God. He may not be interested in interfering with the karma of His own body, just as many Avatars before Him also did not do. Krishna for example, allowed His body to meet its end at the arrow of a hunter (Angada in previous birth) so that the karma of Rama time is cleared off. Ramakrishna Paramahamsa did not ask Mother Kali to cure his throat cancer. Shirdi Sai Baba did not bother to cure His own physical ailments. Bhagawan Ramana Maharshi did not bother to cure the cancer that was affecting his body.
A mere human or an avatar who is fully conscious? Depends on your own perception and your own experience!
