When pimples pop out in strange places such as in your ear or on your arm. What is this?

In brief: Arm acne?

These rather painful pimples are not actually acne, but rather folliculitis.
This translates out as irritations around hair follicles. They are annoying and usually non-infectious. Just because there is a pus bump doesn't mean there is bacteria! hot soaks, and ultimately gentle pressure (and i mean gentle!) will almost always make them go away.
