The muscle on the front of the calf is also called the tibialis anterior muscle, and pain in this muscle may have the following reasons: 1. It may be caused by long-term muscle strain, or muscle inflammation, such as people who stand and walk for a long time or people who do bouncing and running for a long time are prone to tibialis anterior muscle strain, and chronic aseptic inflammation can occur over time. 2. The day before the strenuous exercise, especially after the lower limbs of running, bouncing and other strenuous exercise, resulting in local lactic acid accumulation, lactic acid stimulation of the tibialis anterior muscle, resulting in tibialis anterior muscle pain and so on, usually rest for two or three days, this situation will disappear on its own. 3, may be lumbar intervertebral disc herniation, compression of the nerve roots of the lower extremities, resulting in the lower extremities of the nerve tugging pain, numbness, fatigue and other sensations, especially lumbar lumbar four Five intervertebral disc herniation, directly affecting the nerve sensation of the anterolateral muscles of the calf.
