I had to have my left ear pierced again a year ago. I wore the gold posts up to a month ago to make sure that the hole would not close on the left ear. However, the ear that I had pierced is crusty a lot. The earring that I put on in the morning does not hurt when it is in the left ear but it hurts to put in and take out. What can I do to get rid of the crust. I do not get crusty in the right ear, only the left (the left is the one I had pierced.
