Leg soreness and weakness may be caused by excessive physical activity, or by eating disorders or other factors leading to electrolyte imbalances. Additionally, lumbar disc herniation may also result in leg soreness and weakness. Furthermore, individuals with cervical spondylosis, anemia, or fever may also experience such symptoms.
