Ten days ago, a child experienced three days of viral fever and was diagnosed with an upper respiratory infection. After the fever subsided, the child had diarrhea for three to four days, which improved after medication and three days of intravenous fluid therapy. However, the child has now started to be restless and cry awake at night, sometimes crying loudly. Monthly routine checks show continued viral infection, an ultrasound shows no abnormalities in the abdomen, and the results of the myocardial enzyme test indicate elevated levels of myocardial enzymes, but not related to the viral infection. What should we do?
