One reason is that you will be given some idea of what to expect from the future course of the virus (although everyone is different), and it's also crucial if you are going to be in relationships or having sex, so you can inform partners and take the appropriate precautions and judge the level of risk & how to deal with it.
A crack in the lips could be a herpes outbreak but could also, as has been said, result from chapped lips. Deficiencies in certain vitamins can also cause cuts and cracks in the lips.
