Introduction
Fever generally refers to an elevated body temperature. Weakness and lack of strength in the legs after fever may be caused by lactic acid buildup, malnutrition, electrolyte imbalance, myofascial inflammation, insufficient kidney qi, or other reasons. It is recommended to undergo thorough examinations for an accurate diagnosis and receive treatment under a doctor's guidance to prevent worsening symptoms. During treatment, adequate rest should be taken, excessive physical exertion avoided, and a light diet maintained to help alleviate symptoms.
Fever generally refers to an elevated body temperature. Leg weakness and fatigue after fever may be caused by lactic acid buildup, malnutrition, electrolyte imbalance, myofascial inflammation, or kidney qi deficiency.
1. Lactic Acid Buildup
Excessive physical exertion during fever, or infections caused by viruses or pathogenic microorganisms, may lead to excessive lactic acid production in muscles. If this lactic acid is not fully metabolized, it accumulates and causes symptoms such as leg weakness, muscle soreness, and fatigue after fever. Under the guidance of a healthcare professional, localized massage and warm compresses may help reduce lactic acid accumulation and relieve symptoms.
2. Malnutrition
Insufficient nutrient intake during fever, or increased metabolic consumption of nutrients due to fever, may result in malnutrition, leading to symptoms like leg weakness, dizziness, and fatigue. It is recommended to improve nutritional intake by consuming adequate high-protein foods such as eggs and milk to promote recovery.
3. Electrolyte Imbalance
Excessive sweating during fever can cause significant fluid loss. If fluids are not replenished promptly, it may lead to electrolyte imbalance, resulting in symptoms such as generalized weakness, dizziness, nausea, and vomiting. It is advisable to receive fluid replacement therapy under medical supervision. Commonly used solutions include glucose solution, sodium chloride solution, and normal saline.
4. Myofascial Inflammation
In individuals with pre-existing myofascial inflammation, exposure to cold or damp environmental conditions may trigger fever along with symptoms such as leg weakness, muscle spasms, and numbness of the skin. Local massage and heat application under medical guidance are recommended to improve blood circulation, reduce inflammation and pain, relax muscles, and promote blood flow for symptom relief.
5. Kidney Qi Deficiency
The kidneys play an important role in regulating the body's circulation of qi and blood and maintaining yin-yang balance. Deficiency of kidney qi may cause symptoms such as lower back pain, leg weakness, sensitivity to cold, and fever. Adequate rest and hydration are recommended. When necessary, antibiotics such as Cefradine Capsules, Cefixime Capsules, or Penicillin V Potassium Tablets may be prescribed under medical supervision to alleviate symptoms.
It is recommended to seek medical attention at a hospital for a thorough evaluation and accurate diagnosis, and to receive appropriate treatment under medical guidance to prevent worsening of symptoms. During treatment, ensure sufficient rest, avoid overexertion, and maintain a light diet to support recovery.
