What causes soreness and pain in both calf muscles?

Generally, pain in both calf muscles may be caused by factors such as excessive exercise or fatigue, aging, calcium deficiency, lower extremity varicose veins, lumbar disc herniation, and other conditions. It is recommended to seek medical attention promptly and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Excessive Exercise or Fatigue

Extended walking, running, climbing mountains, or similar activities can lead to overuse of the calf muscles, resulting in the accumulation of metabolic byproducts such as lactic acid, which causes soreness in both calves. Appropriate rest, reduced physical activity, and physical therapies such as warm compresses and massage are recommended.

2. Aging

As people age, muscle elasticity decreases and blood circulation slows down, making calf muscle soreness more likely. Regular engagement in moderate physical exercise can help strengthen muscles and improve flexibility.

3. Calcium Deficiency

When the body lacks calcium, muscles may experience cramps and spasms, leading to soreness in both calves. Increasing intake of calcium-rich foods such as milk and soy products is beneficial. Additionally, regular sun exposure can promote calcium absorption.

4. Lower Extremity Varicose Veins

Lower extremity varicose veins are often associated with prolonged sitting or standing, which impedes venous blood return and leads to blood pooling in the legs. Chronic blood stasis can cause calf muscle hypoxia, resulting in soreness in both calves. Symptoms may also include leg heaviness and edema. Under medical supervision, medications such as sodium aescinate tablets, xuesaitong soft capsules, or ceftriaxone sodium for injection may be used for treatment.

5. Lumbar Disc Herniation

Lumbar disc herniation is often related to poor sitting posture and may compress the sciatic nerve, causing radiating pain in both calves. This condition is typically accompanied by lower back discomfort and numbness in the lower limbs. Patients are advised to follow medical instructions when using medications such as Gentongping granules, Tongluo Qutong ointment, or diclofenac sodium sustained-release tablets to relieve symptoms.

In daily life, it is important to avoid prolonged standing or walking. Regular stretching and relaxation of the calf muscles—such as calf massage or soaking feet in warm water—are recommended.
