Dr. Jiang Weimin
On day 4 of influenza B, leg muscle soreness and weakness are common symptoms of muscle pain, possibly caused by muscle fatigue or overexertion, frequently seen in young individuals or those with excessive training. This soreness and weakness may also result from inflammation or wound infection, or be associated with various diseases such as rheumatism, rheumatoid arthritis, or spinal disorders, which could lead to long-term chronic pain. Therefore, it is essential first to consult a doctor for diagnosis to determine the underlying cause, then adopt appropriate treatments based on the condition—such as heat therapy, medication, or rehabilitation therapy—to help relieve symptoms, slow disease progression, and promote recovery.
