The toenail keeps growing into the flesh because of the following reasons: 1, it is considered to be caused by wearing tight shoes and socks. The soft tissues next to the nail are stimulated for a long time because of tight shoes and socks, causing the toenail to grow into the flesh. 2, consider that the nail is always growing into the flesh because the toenail is usually trimmed too short. The nail grows into the flesh, the so-called ingrown nail, and this situation is likely to cause nail infection attacks in the long-term progress. The typical symptoms of nail fungus are redness, swelling and pain in the soft tissue next to the nail, and in severe cases, pus. Once nail infection is diagnosed, it needs to be treated with symptomatic anti-inflammatory treatment, and if it has become pus, the abscess needs to be incised and drained, and then the nail is removed after the inflammation of the abscess has subsided. The nail bed should be destroyed to prevent the nail from growing into the flesh, and loose shoes and socks should be worn.
