I found this wedged under the nail bed.

皮肤碎屑。

That brand new nail continues to grow slowly sliding along a nail bed of soft tissue.

全新的指甲会继续生长，沿着软组织的甲床缓慢生长。

Your nail beds are gonna get infected.

你的甲床会被感染的。

Instead, white lines that go across the nail, parallel to the nail bed, are usually a sign of trauma to the nail.

相反，穿过指甲并平行于甲床的白线通常是指甲外伤的迹象。

In severe cases, it can even cause nail disorders like ridges, white spots, and separation of the nail from the nail bed.

在严重的情况下，它甚至会导致指甲疾病，如脊线、白斑和指甲与甲床分离。
