couple rules on stretching. you may know these, but they bear repeating:
1. don't stretch for flexibility unless your muscles are already warm from working.
2. ballistic stretching isn't all that good for flexibility, and you can easily injure yourself.
3. if an area hurts, don't stretch it for flexibility until it's all-the-way better. however, you can run that joint through much of its range of motion to keep blood going to the area -- this is actually a good thing.
remember that, when you stretch a joint from only one end, it can only stretch it so much. adding the other end to the mix makes a huge difference. think hamstrings: sitting down with your back straight and legs out in front of you is only stretching your hammies from the bottom end by the knee. now, bending forward at the hips and trying to touch your nose to your toe pulls the hammies from the upper end as well and, thus, makes the stretch more complete.
with this in mind, be careful when you switch from single-ended stretches to doubles. your soreness could be a sign that you went a bit too far.
