Why do my legs feel sore, painful, and weak?
Disease description:
Recently, my legs have been feeling sore and weak, and even climbing stairs feels strenuous. Sometimes, I also experience a tingling sensation in my legs. I'm not sure if it's because I've been walking too much lately. I'm very concerned—what could be causing this?

Leg pain and weakness can be caused by various factors. Below are some common possible causes:
1. Overuse or sports injuries: Prolonged standing, walking, or strenuous exercise may cause leg muscles to feel fatigued and sore.
2. Disc disease: Conditions such as lumbar disc herniation may compress nerves, causing weakness and pain in the lower limbs.
3. Arthritis: Related to autoimmune disorders and joint overuse, arthritis can cause pain, swelling, and stiffness.
4. Exposure to cold: Inadequate leg warmth can impair blood circulation, potentially causing local soreness, numbness, and weakness.
5. Ankylosing spondylitis: This condition may be caused by genetic factors, infection, or immune dysfunction, and can lead to leg muscle damage, causing pain and deformity.
6. Muscle diseases: Conditions such as myasthenia gravis and inflammatory myopathies directly affect muscle function, resulting in weakness.
7. Calcium or potassium deficiency: Electrolyte imbalance may also lead to muscle weakness and cramps.
8. Circulatory problems: Conditions such as varicose veins and deep vein thrombosis can impair blood return in the lower limbs, causing heaviness and pain in the legs.
