Surfers Ear

This is a medical condition (called exostosis) where a bony growth within the ear canal grows due to irritation of the bone by persistent exposure to cold (water and/or air). Cold air (and even warm air) blowing into a wet ear lowers the temperature due to evaporation which stimulates the bony growth. The cure for this is nasty – so prevention is the key. Use your ear plugs!!!
