For over a month now, I've had this bump behind my right ear. I had someone open it, and drain it. Puss came out, and it felt better for a day or two. It never went away- it's still there. If you touch it- it hurts, sleeping on it hurts, touching the ear lobe also hurts. The small bump is hard. It is located right behind my ear lobe. any idea what it is? Should I go see the doctor? I do wear galsses...could that have irritated it? I have had MRSA before, but this is not it. Thanks.
