Patient: Hello, about 2.5 weeks ago I felt a painful to the touch small bump behind my ear, where the crease of my ear meets my head. It was very sensitive to the touch, like a pimple, but never came to a head or erupted. Since then the sensitivity has gone away unless I press hard but the bump still remains. Should I be worried?
