When that happened to my newborn, they cauterized it in the Dr's office to seal it off. It did ooze a bit here and there afterwards, but it turned out fine. As far as pain, I'd say its uncomfortable, but while its open, it can still have a chance for infection, so address your concerns with the Dr again or the pediatrician so something can be done so it can start healing properly. G'luck!
