What might be causing my itchy inner ear?

What could be causing itchy inner ear?!

• For the past week or so, the inside of my left ear is itching like crazy. It feels like right in the part I can reach with my finger, but I never "satisfy" the itch. It doesn't feel all the way down in the canal, though I suppose anything is possible. I have no fluids or excess wax coming out of my ear, no other symptoms. The itching comes and goes. It'll come for a few hours and then be gone for a few. When I lay down on it it starts to itch again. What could be causing this?

• Answer:

  There is something in there irritating the skin. Use an ear drying solution...that contains alcohol and use that to perhaps stop the itch. http://www.med.umn.edu/otol/library/swimmers.htm go from there to perhaps find a solution.
