We just got back from another appointment. The doctor says that the muscle fatigue from racing can cause the enzymes to stay at high levels in the body for weeks. So, Mike is going to the race this weekend (which I'm totally against!). After that, he isn't going to race for a month, go back and test again, and see if the enzymes went down. Doc also says he has a heart murmor, but that may not be a big deal. The doc seemed confident that this is all probably nothing, but said that we'll keep an eye on it and do further tests. He ordered a whole series of tests.

The doctor says that he doubts that the previous accident caused any damage to the heart, he says there is no way they wouldn't have caught that.
