Have you looked at your earlobes lately? I did and I have them so I figured it couldn't hurt to ask some questions before anyone diagnoses from just checking the internet.
I dropped a note to my personal doctor to ask having noticed them myself if it's something to be concerned about. Here's his response back to me.
Michael. Some very small studies 15 years ago raised the possibility of an association between ear lobe creases and an increased risk of heart disease. Other studies have not supported this. There have been no large well designed studies to support ear lobe creases as a risk factor. Bottom line, don’t worry about your ears.Have a wonderful holiday. Harry
My advice to you would be ask your doctor and don't worry about what's on the internet!
