Eli5 Why does hitting your funny bone hurt so dang bad?
In: Biology
Right above the elbow right? Not a lot of cushion (fat or muscle), so the nerve is more exposed to the blunt force. Nerves are sensitive to and are what help detect things like pressure and temperature hence why it’s so painful.
This is my observation though experience and what I think is going on. An MD could probably give a more precise and correct reason.
When I was a kid I’d prod around the funny bone area and was able to poke the nerve and it would make my whole arm tingle for a couple seconds (didnt hurt).
