ELI5: Does touching bones(for example if I had a deep cut or a bad break that exposed bone) hurt?
gpt
You can literally palpate your bones through your skin. Does it hurt when you do this? No. Any sensation is the nerve endings in your skin. With that being said, once you enter the bone, you can feel pain. In certain emergency situations, the inside of the bone has to be accessed in order to administer life saving medications. The person does not usually react to the puncturing of the bone, but they do experience severe pain when saline and/or medications are pushed into the bone marrow.
