If you experience weakness in your limbs during a cold, it is important to consider that this may be caused by the invasion of bacteria or viruses, leading to muscle soreness and weakness. There may also be accompanying symptoms such as mild fever, chills, or fatigue. It is advised to pay attention to these signs and visit a hospital for a routine blood test to identify the cause of infection. Subsequently, take the appropriate anti-inflammatory and anti-infection medications to treat and alleviate symptoms. During this period, it is crucial to rest adequately, avoid overexertion, maintain a positive mood without too much stress, avoid staying up late, and cooperate actively with medical treatment to ease symptoms. If you notice an increase in body temperature, you should use physical cooling methods or take fever-reducing medication to lower your temperature.
