Sores/lesions on the ear..something worse?

last month i developed an itchy small spot on the enterance of my ear that started as a small pimple, and clear fluid comes out when i its it. THen it started spreading , with one of these lesions going away and another one poping up, unitil it went to my earlobes, where it cleared up on its own. Now, the same thing is developing in my other ear, in the same place. Any idea what this is????
