Why does my lower back hurt after standing for a long time?

Hello, your symptoms may result from prolonged standing, which can cause strain or injury to the lumbar muscles. In such cases, massage or heat application to the lower back can improve local blood circulation and effectively relieve symptoms. Additionally, avoid maintaining the same posture for extended periods—especially prolonged standing—and perform gentle lower back movements periodically to help alleviate discomfort. If the low back pain is severe, over-the-counter analgesics may be taken for symptomatic relief. I hope this information is helpful to you. Wishing you good health!
