Tingling in the breasts during breastfeeding is normal if the pain is not particularly severe. This is because the increase in milk secretion leads to the expansion of the milk ducts, which will cause a tingling sensation. If there is a hard lump in the breast, it is not normal, indicating that it is caused by milk stagnation, and needs timely symptomatic treatment. If there is no hard lump, no need to treat, usually try to pay attention to hygiene, pay attention to cleaning, do not eat spicy stimulating food. You should also pay attention not to violent bumps, if violent exercise or bumps, will easily lead to milk stagnation, resulting in hard lumps. During this period, you should also drink some soup in moderation, to promote the role of milk secretion, but also to improve the nutrient content of milk, drink more chicken soup, fish soup, pork chop soup, pig’s trotters soup and other foods.
