It is now February 20, 2008. It is 2:00 am. I was sound asleep until I was woke up by a pop sound. I felt a pop pressure in my throat and it felt swollen and popped and when this happened I felt pressure pulling on my ribs and on my chest. My chest shook a lot for about half and hour and it felt really cold, like a cold ice sensation and my chest was shaking and I had a hard time breathing. After my chest stopped shaking I felt the inside really hot and warm. My ribs and chest hurt a lot. I do not have any insurance. I wish I did.
