Neosporin will often clear it up on it's on. Just apply a bit at the inside edge. with a clean finger apply about the width of a pencil, pull down the inside corner and wipe it into the little pocket. Use the regular ointment, not lotion. I wouldn't be surprised if it's somewhat better in the morning if You apply it soon. This isn't harebrained, it's a long time remedy.
Good Luck.
