I hope your Murmur isn't a serious one. I was born with a murmur, have had it my entire life, it's never held me back from anything. I was a cheerleader for 6+ years, I tend to run out of breath quickly, and need to take short "breaks" but I don't have any physical restrictions, and the Drs aren't worried about it. Please keep us updated, I'll keep you in my thoughts.
