Is it better to dig out a splinter no matter how painful, or to leave it alone? What should I do if the splinter is from pressure-treated wood that won’t deteriorate?
If you can get the splinter out, great! If you can’t, let it go. Even if the splinter doesn’t deteriorate, it won’t cause you any harm.
Sometimes, splinters imbed themselves so deep in the skin that you can’t get them out. Even at the hospital, it can’t be always removed. When this happens, your body’s defenses wall off the splinter, and sometimes even develop a pus pocket around it. Don’t worry about this. With time, it’ll probably work its way out.
