The cause of one thick calf and one thin calf may be the long-term uneven force on both legs, one side of the nerve damage (such as tibial nerve), lumbar spine disease.
1. Long-term uneven force on both legs: when the human body is in sports or heavy physical labor, it is used to exert force on one side of the leg, while the other leg is in the auxiliary state for a long time, over time, it may result in the muscular development of the leg that focuses on exertion is more robust, while the other is more thin.
2. Damage to one side of the nerve: If the leg trauma caused by one side of the leg nerve damage such as the tibial nerve, it may lead to the innervation side of the leg muscle disuse atrophy, resulting in uneven thickness of both sides of the calf.
3. Lumbar spine disease: such as lumbar disc herniation caused by lower leg pain on one side of the lower leg, in order to alleviate the symptoms, the patient will shift the center of gravity to the healthy side of the leg for a long time, resulting in the affected side of the leg with less force, and over time there will be atrophy phenomenon, resulting in one leg thick, one leg thin.
In addition to the above reasons, diseases such as pyriformis syndrome and sciatica may also cause the above symptoms. If the above symptoms are severe or accompanied by other symptoms, you should go to the hospital in time to find out the cause of the disease and give targeted treatment.
