One way you can check the limbs for damage is to run a cotton ball all over the front and back surface. If there are any splinters or cracks starting or have developed they will tend to snag small strands of cotton, making them more easily visible. You can also do the same thing over the riser. From what I've seen and read the limbs are more likely to have been damaged than the riser, if there is any damage to any part of the bow.
