How To: 9 DIY Ways to Painlessly Remove Splinters from Your Skin
7/29/13 the baking soda TOTALLY worked! The deep splinter actually worked its way out completely on its own over the course of a few hours. I pulled off the bandaid and the splinter was sitting on my skin a bit away from the hole. http://thesecretyumiverse.wonderhowto.com/how-to/9-diy-ways-painlessly-remove-splinters-from-your-skin-0139135/
See How to Remove a Splinter with less pain. The baking soda/water paste method described here is best for tiny, invisible splinters, or deeply-embedded ones. The baking soda paste will cause the skin to swell and push the splinter out. It's best used after other methods, since it will make the other methods (tape, tweezer ,needle) more difficult because your skin will be slightly swollen. See link for steps.
