In 2006, my husband, Bob, was injured by an improvised explosive device while on assignment in Iraq. After he awoke from a five-week-long coma -- also known as the longest five weeks of my life -- he was in a tremendous amount of pain. His doctors in Baghdad had saved his life by removing 16 centimeters of his skull, so most of us can't even imagine how that must have felt. Doctors implanted a skull liner after four months, but during that time, Bob was in extreme pain. Even sneezing hurt him immensely. I can tell you from personal experience, there is nothing worse than seeing a loved one in pain
