What causes pain in the lower leg bones after standing for a long time?

Generally, pain in the lower leg bones after prolonged standing is caused by physiological factors, but it may also result from pathological conditions such as lumbar disc herniation or degenerative osteoarthritis. It is recommended to visit a hospital for a thorough examination to determine the exact cause.

1. Physiological Factors

Standing for extended periods can lead to calf muscle fatigue and poor local blood circulation, resulting in pain in the lower legs. It is advisable to rest more and apply local massage or heat therapy to improve blood flow and alleviate symptoms.

2. Pathological Factors

1) Lumbar Disc Herniation

In lumbar disc herniation, the nucleus pulposus protrudes through a ruptured annulus fibrosus, causing lower back pain. If the herniated tissue compresses spinal nerves or the cauda equina, it can cause radiating pain, leading to deep bone pain in the lower leg. When pain is significant, medications such as celecoxib capsules, diclofenac sodium sustained-release tablets, or ibuprofen sustained-release capsules may be taken under medical guidance to relieve symptoms.

2) Degenerative Osteoarthritis

Degenerative osteoarthritis results from cartilage degradation and reactive bone proliferation at joint margins and subchondral bone, which may cause lower leg pain after prolonged standing. Treatments such as percutaneous electrical nerve stimulation (PENS) or thermotherapy, administered by qualified physicians, can help improve local circulation, reduce inflammatory responses, and relieve symptoms.

In addition, lower limb phlebitis may also cause similar symptoms. If discomfort occurs, prompt medical evaluation is necessary to avoid delaying diagnosis and treatment.
