Diastasis Recti is the separation of the vertical abdominal muscles, called the Rectus Abdominis muscles. Pregnancy causes stretching of the abdominal muscles. Sometimes after delivery, the muscles do join back up in the center, leaving a vertical thin area of separation. This can sometimes be so thin that it allows your "insides" to bulge outward, especially when sitting up, or straining. This pressure can cause pain. Diastasis is different than a hernia, which is basically a hole through which your "insides" can actually push through the hole and get caught. This can sometimes become an emergency medical problem. You should see a doc just to be sure of which you have.
You may have pain either from a hernia that needs to be repaired or due to the pressure caused by the diastasis
