Splinters are everyday injuries commonly involving a small shard of wood, glass, metal, plastic or a thorn that becomes embedded in the skin and the soft tissue underneath.
The outer skin layer, known as the epidermis, has a high level of pain receptors. The layer just underneath, called the dermis, has even more of them, potentially making such injuries very painful.
Knowing how to remove a splinter may not be a matter of life and death. However, good technique can relieve someone from ongoing pain or subsequent complications.
