Leg soreness and weakness in men can be caused by a variety of reasons, such as overwork, malnutrition, lumbar disc herniation, anemia, hypokalemia, etc.

1. Overwork: Long-term physical labor or strenuous exercise leads to excessive fatigue of the leg muscles, resulting in a feeling of soreness and weakness. In this case, symptoms usually resolve gradually with proper rest, massage, and warm compresses.

2. Malnutrition: An unbalanced diet and a lack of nutrients such as protein, vitamin D, and calcium can affect the normal function of muscles and bones, causing leg soreness and weakness. At this time, it is necessary to adjust the diet structure and increase the intake of foods rich in these nutrients, such as milk, eggs, fish, soy products, etc.

1. Lumbar disc herniation: A herniated disc compresses a nerve, which may cause symptoms such as soreness, weakness, pain, and numbness in the innervated area of the leg. Treatment includes physical therapy, medications (eg, nutritional neurological drugs such as methylcobalamin, vitamin B0), and, in severe cases, surgery.

12. Anemia: Iron deficiency anemia, megaloblastic anemia, etc., lead to a decrease in the oxygen-carrying capacity of the blood, and the muscles cannot get enough oxygen supply, resulting in soreness and weakness in the legs. Treatment requires identification of the type of anemia and targeted iron supplementation (eg, ferrous sulfate), folic acid, and vitamin B0.

5. Hypokalemia: Insufficient potassium intake, excessive excretion or intracellular potassium transfer lead to a decrease in blood potassium concentration, affecting muscle excitability and contraction function, and leg soreness and weakness. This can be corrected with oral or intravenous potassium preparations such as potassium chloride.

6. Endocrine diseases: such as hypothyroidism, diabetes, etc. In hypothyroidism, the metabolic rate decreases, which can lead to muscle weakness. Diabetic patients with poor blood sugar control may also have leg symptoms if long-term hyperglycemia damages nerves and blood vessels. Treatment is focused on the underlying disorder and controls thyroid function and blood sugar levels.

7. Nervous system diseases: such as cerebral infarction, spinal cord lesions, etc., which affect nerve conduction function and lead to leg weakness. Treatment may require medications, rehabilitation, or surgery, depending on the condition.

In conclusion, the causes of leg soreness and weakness in men are complex. If the symptoms persist or are accompanied by other discomfort, you should go to a regular hospital in time for relevant examinations (such as blood count, electrolytes, lumbar CT or magnetic resonance imaging, etc.) to determine the cause and take appropriate treatment measures.
