"Why Do My Legs Feel Tired and Uncomfortable?"

Thigh fatigue may be caused by potassium deficiency, local aseptic inflammation, lumbar disc herniation, and other factors.

1. Potassium Deficiency: Severe potassium deficiency in the body can lead to hypokalemia, affecting local bones and muscles. This may cause soreness and weakness in the thighs and may also cause numbness of the mouth and fingers. The treatment for hypokalemia mainly involves potassium replenishment, such as through food, oral medications, and intravenous infusions. Commonly used oral medications include potassium chloride and potassium citrate.

2. Local Aseptic Inflammation: If there is aseptic inflammation in the thigh area, such as synovitis or femoral head necrosis, it can cause soreness, weakness, and other symptoms in the thigh. Treatment can involve prescribed corticosteroids, non-steroidal anti-inflammatory drugs, immunosuppressants, and antihistamines, such as aspirin, dexamethasone, tacrolimus, and loratadine.

3. Lumbar Disc Herniation: Patients with lumbar disc herniation usually experience compression of local nerve roots, causing symptoms of thigh fatigue. This can be improved through physiotherapy, massage, oral medications, traction, and other methods. Patients with thigh fatigue are advised to promptly undergo comprehensive examinations at the hospital to identify the cause and take corresponding treatment under the guidance of a doctor. During treatment, patients should maintain a good lifestyle and dietary habits to promote symptom improvement.
