It is normal to have hard lumps in the breast milk, and there is no fever, pressure pain, etc. You do not need to take special treatment. Returning to milk usually takes a few days, during which time there is still milk secretion, and when more milk is secreted and there is no way to discharge it completely, it will be stagnated in the mammary ducts and form lumps, which is generally normal in this case. If there is little milk left in the breast, the lump is small and the swelling of the breast is mild, and there is no localized redness or swelling, you can use a wet towel to apply localized hot compresses to promote the absorption of the accumulated milk. The remaining milk in the breast is more, the hard lump is relatively large, but no local redness and swelling, you can also use a breast pump to suck out part of the milk, but avoid completely empty milk, you can also fry malt decoction to promote the return of milk. Returning to the milk with hard lumps is generally normal, but the occurrence of fever, breast pressure and pain is abnormal, need to consult a doctor in time.
