Hello everyone! I have lactostasis ? The lump won't go away, and I pumped out all the milk with a breast pump until it was completely drained, but the bump is still there, I massaged it hard, I'm afraid that mastitis will happen and I'll have to see a surgeon, it's been two days now, but it doesn't hurt and there's no fever. What should I do??
