What disease is it when the child's breast itches after drinking milk?

Patient's question:

Hello:
Every time the child finishes drinking milk, my breasts will feel itchy for a while. Is there anything wrong?

Doctor's answer:

Mom, this phenomenon should be some breast blockage. You need to use a warm towel to apply it to the breast to soften it and use a breast pump to unblock it. Usually, you should let the baby suck more.
