First I would like to say, WELCOME TO LBT! As far as the heat is concerned I sometimes get the same thing and my Dr. said I was fine. Yes, I sleep on my stomach but I can't stay in the same position for long and I don't know if it's a mental thing with the port area or what but I just can't! We're a day apart by the way. :confused: You're doing really great so far, keep up the good work.
