Abdominal pain is more common when coughing. First of all, coughing causes violent heaving of the chest cavity and also pulls the abdominal muscles. Repeatedly vibrating the abdominal muscles and pulling the abdominal muscles can cause abdominal pain, which is often relieved by cough suppressant treatment. If it is an irritating dry cough, it is recommended to use compound licorice combination or fenugreek syrup for cough relief. For coughs with phlegm, expectorant medications are recommended, such as tranylcypromine oral solution or tranylcypromine hydrochloride or pulmonary cough combination. In addition, if a child has abdominal pain with cough, mesenteric lymphadenitis cannot be excluded. Because coughing is often an inflammatory phenomenon in the body, it can also easily trigger the development of mesenteric lymphadenitis. The first thing to do is to take your child to the hospital for an abdominal ultrasound, and if there is indeed mesenteric lymphadenitis, you should still treat your child with antibiotics, such as pediatric cefixime pellets.
