why do the insides of my ears hurt sometimes when i go running in cold weather?

not really sure, but my guess would be that it's something akin to why some people's teeth hurt when they eat ice cream. when bone nerves get cold, they can really put up a fuss. lots of bone is close to the surface around the ear. have you tried wearing ear muffs?

lots of blood flows through your ears. cold causes construction of blood vessels (everywhere, not just your ears) and this constriction reduces blood flow and thus oxygen flow into the delicate and sensitive ears. restricted oxygen = headache. also the tensor tympani, which are the muscles which hold the ear drum taught, are subject to the cold just like any other muscle.

that is an absolutely amazing answer. thanks sam!

I wonder if this is connected also to why sometimes ears hurt in cold water--and then develop swimmer's ear?

Does the pain occur in your outer or inner ear? If in your inner ear, it is possible the exertion causes you to breathe heavily through your mouth rather than your nose, and the air is not sufficiently warmed by your body before it hits the passageways leading to your inner ear that ordinarily equalize pressure on your eardrums.

a pleasure, evan!
