Is it normal for my baby to have small bumps on his neck and behind his ears?

Question 1: My daughter was one year and three months old. When she was seven months old, she found a small lump behind her left ear. When she went to the clinic, she said it was a fever and her lymph nodes were swollen. I occasionally have symptoms behind my right ear, but they go away again after a few days. Is it because the lymph nodes are inflamed? Do I need to go to the hospital for a checkup? Dr. Luo Zhen’s answer: These are lymph nodes. Almost everyone can feel or have felt them in one or more places such as the neck, in front of and behind the ears, armpits, groin, popliteal fossa, etc. They are as small as mung beans, as big as broad beans, or as large as broad beans. Superficial lymph nodes with subcutaneous movement, clear boundaries, no tenderness, and no local redness or swelling. This is the human body’s innate immune barrier second only to the skin. It is harmless to the human body. There is no need to be nervous or to treat it. If there are other symptoms, let it go. Doctor take a look. Question 2: My baby is one year and 8 months old. He walked normally before, but in the past week he mostly walked on one heel, and sometimes he walked normally again. We went to our hospital and took X-rays, but couldn\’t find the cause. The doctor said it was caused by a cold before and asked him to be hospitalized for fluid transfusion. I would like to ask what happened to the baby? How to treat? Dr. Cui Lixia answered: Infusion is not recommended for the time being. If you can walk normally and have no painful symptoms, the problem should not be serious and you can continue to observe. After a cold, it usually causes unilateral joint synovitis and walking limp. It is necessary to reduce activities and observe for a week. Question 3: After two days of engorgement, my milk supply decreases. What should I do? Is it true that my mother-in-law said that breast pumps can cause milk reversion? Dr. Pan Guilan’s answer: Drink more soups and water, and let the baby suck more, especially at night when milk secretion is strong, so let the baby suck more. Breast pumps will not cause milk resumption. If you are worried, go to the hospital and have an obstetrician perform a hand examination to rule out any blockage, lumps, or engorged milk.
