If you have back pain in the middle of the spine while breastfeeding, you need to consider that it is caused by lumbar spine or muscle injury, because women often need to hold the child during breastfeeding, if the posture is not correct or too long, it will easily lead to lumbar muscle strain and other diseases. If the symptoms can be relieved by local hot compresses or massage, it is mostly considered to be due to lumbar muscle strain, at this time the patient should pay attention to more rest and hold the child as little as possible. If the spinal pain is accompanied by pain or numbness in the lower extremities, you should be alert to diseases such as lumbar disc herniation, and if necessary, you can see a doctor for a lumbar spine CT examination and give the appropriate treatment measures according to the results. If a woman has poor digestion, such as gastritis, gastric ulcer or other diseases, it is also possible that the back pain is caused by ulcers in the duodenal bulb, so you need to pay attention to a light diet, avoid spicy and irritating food, and if necessary, see a gastroenterologist for gastroscopy and appropriate treatment.
