If back pain occurs when you have a cold, it is important to pay attention to it, especially to do an electrocardiogram, because sometimes when angina pectoris or myocardial infarction occurs, it can also lead to back pain, and a cold can trigger these conditions, which is very dangerous, and doing an electrocardiogram can help diagnose angina pectoris or myocardial infarction. If there are no obvious abnormalities in the ECG, an MRI of the back is also done to observe any lesions in the thoracic spine. If there is no obvious abnormality, muscle pain is often caused by a cold, and it is better to use cold medicine to relieve the effect, such as aminogalactam capsule, Vitamin C silver warp tablet, Sensitive Health or cold spirit granules to treat adults. For children, you can use pediatric black forsythia fever granules or pediatric cold and flu fever granules, pediatric aminophenol pseudo-lax dispersible tablets for treatment. If the back pain is accompanied by fever, you need to use antipyretic drugs to relieve the pain, such as oral ibuprofen suspension.
