That soreness is caused by microscopic tears in the muscle fibers. In order for them to get stronger, you have to let them heal! So exercising them vigorously may actually hinder the process. That doesn't mean you have to sit on your butt and be inactive. Light exercise like walking or yoga can help you feel better.
Do know that the presence (or lack) of stretching has nothign to do with soreness the day after; stretching won't prevent it (it can help make it less painful, but it won't stop it) because it's caused by those aforementioned torn muscle fibers. It sounds bad, but this is how our bodies get stronger. :)
So listen to your body. It's not about making excuses, it's about increasing your risk of injury and slowing your strength-building. You want to avoid overtraining!
