The causes of sudden pain in the calf include muscle strain around the calf, varicose veins in the calf, lumbar intervertebral disc herniation, tumors in the calf bone or soft tissues and so on.
1. Muscle strain around the calf: due to factors such as long standing and long walking, overwork, cold stimulation and so on, the muscles around the calf such as tibialis anterior muscle, fibularis longus shortus and so on are strained, which in turn trigger the symptoms of pain in the calf.
2. Varicose veins of the calf: it is common in people who need to stand for a long time due to the special nature of their work. The obstruction of venous return in the lower limbs leads to a sharp increase in venous blood volume, resulting in localized venous dilatation. The varicose veins will block the normal blood flow, resulting in sudden pain in the lower legs.
3. Lumbar disc herniation: When suffering from lumbar disc herniation, it compresses the sciatic nerve, causing symptoms of radiating pain in the calf position.
4. Tumor of calf bone or soft tissue: the incidence is low, but we should be alert to the appearance of this disease. The main manifestation is the continuous progress of pain in the calf, which is most obvious at night.
For patients with sudden pain in the calf, it is also necessary to exclude calf fracture, muscle and ligament rupture and other diseases, and it is recommended to go to the hospital in time to receive relevant examinations to clarify the specific conditions and timely treatment.
