Not life threatening.... sounds like good news as opposed to the opposite at the moment. PK has great advise! A second opinion is a good thing. We are talking about you and your life. To be thorough is every bit your right. Never hesitate to ask questions, any single thing you don't understand. Doctors are to be appreciated, but they are working for you! If you don't feel comfortable asking have Heather ask! Make sure you are comfortable with understanding what is happening with you and your body. : ) My thoughts and prayers are with you!
