What causes soreness and pain in the lower leg?

Generally, soreness and pain in the lower leg may be caused by factors such as muscle fatigue, exercise injury, poor blood circulation, sciatica, or arthritis. If bodily discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:

1. Muscle fatigue: Prolonged standing, walking, exercising, or overusing the calf muscles may lead to lactic acid buildup in the gastrocnemius muscle, causing soreness. This can be relieved by reducing physical activity and ensuring adequate rest.

2. Exercise injury: Excessive exercise or improper exercise posture may result in overstretching or overuse of the calf muscles, leading to soreness. It is recommended to perform proper warm-up and stretching exercises before physical activity and to control exercise intensity and duration to improve symptoms.

3. Poor blood circulation: When blood circulation is impaired, lactic acid produced by muscle cells cannot be cleared promptly, resulting in lactic acid accumulation and subsequent muscle soreness. Therefore, soreness in the lower leg may be due to poor circulation. Patients may follow medical advice to use medications such as Xuesaitong tablets, Musk anti-inflammatory and blood-activating plasters, or Ligustrazine phosphate injections to improve circulation.

4. Sciatica: Sciatica refers to pain caused by compression or inflammation of the sciatic nerve, commonly due to lumbar disc herniation, lumbar spinal stenosis, sacroiliac joint arthritis, or other conditions that compress the nerve. This compression may cause pain and numbness in the calf muscles and skin. Under medical guidance, patients may use medications such as Eperisone Hydrochloride tablets, Celecoxib capsules, or Mecobalamin tablets to alleviate symptoms.

5. Arthritis: If a person suffers from arthritis, it may cause edema in tissues surrounding the joints. When inflammatory factors are released, they stimulate peripheral nerve endings, leading to symptoms such as pain, swelling, and stiffness. In severe cases, soreness in the lower leg may also occur. Patients may follow medical advice to use medications such as Diclofenac Sodium sustained-release capsules, Glucosamine Sulfate capsules, or Qingpeng ointment to relieve symptoms.

In daily life, it is recommended to consume foods rich in protein, vitamins, minerals, and other nutrients—such as eggs, lean meat, tomatoes, apples, etc.—to replenish energy and maintain overall health.
