Cold and flu only have back pain symptoms can not judge which type of cold, the common cold belongs to the upper respiratory tract infection, and influenza has some difference. The common cold is caused by viral infections, mainly manifested as nasal congestion, runny nose, as well as coughing, coughing up phlegm, sore throat, hoarseness, etc., the more serious can also have fever, body aches, cold and other systemic symptoms. Influenza nasal symptoms are generally lighter, the body is more serious such as generalized pain, high fever, etc., mainly caused by the influenza virus, and sometimes can cause a small-scale epidemic. Therefore, since both of them may have back pain or generalized pain, it is not possible to differentiate them solely by the symptom of back pain, and it is necessary to combine them with the specific conditions of the patients and, if necessary, with some laboratory tests, such as blood tests and nucleic acid tests of influenza viruses, to make a judgment. In addition, cold and flu can be combined with other diseases to cause back pain symptoms, such as osteoarthritis, lumbar disc herniation. It is recommended that people with cold and back pain should consult a doctor in time, complete the relevant laboratory tests to clarify the cause of the disease, and follow the doctor’s instructions for reasonable and standardized treatment.
