Influenza B with high fever and thigh pain

One relatively common cause of high fever and thigh pain is influenza B, which often occurs during seasonal changes or sudden temperature fluctuations. Patients typically present with symptoms such as fever, thigh pain, and sometimes coughing and runny nose, with body temperature frequently exceeding 38°C. The following measures can be taken for influenza B-related high fever and thigh pain: 1. Early medication—patients are recommended to use antiviral, antibacterial, and anti-inflammatory drugs, such as amantadine or penicillin. 2. Drink plenty of fluids to maintain hydration and support recovery. 3. Enhance self-regulation—get adequate rest, stay warm, and prevent the flu from developing into pneumonia. 4. Perform routine medical check-ups and initiate timely treatment to prevent progression into other complications.
