The causes of tibialis anterior muscle pain when pressed may be tibial fasciitis, lactic acid accumulation, muscle strain and so on. 1. Tibial Fasciitis: Tibial Fasciitis is a sterile inflammation of the fascia of the tibia induced by strain and environmental stimuli. Clinically, it is mainly manifested as soreness and pain in the lower leg, which may be accompanied by pain in the tibialis anterior muscle when pressed. 2. Lactic acid accumulation: walking or running for too long can lead to anaerobic fermentation in muscle tissues and a large accumulation of lactic acid, which can lead to soreness and pain in the calf as well as tibialis anterior muscle pressure pain. 3. Muscle strain: due to strenuous exercise and other conditions, the tibialis anterior muscle and other soft tissues are damaged under the action of tensile force, which can also be accompanied by swelling and activity limitation. Tibialis anterior muscle pain when pressed may also have other reasons, it is recommended to go to the hospital in time to improve the leg CT, MRI examination, after a clear diagnosis to give targeted treatment or treatment.
