What do those white lines on your fingernails mean?
Where do those white lines on your nail beds come from?
Chances are at some point in your life you've had white blob/lines on your fingernails, and wondered where the heck did these come from?
Well, we've got the answer for you. They're caused by minor trauma to the nail, meaning at some point during your fingernail's lifespan, you must have crushed the nail against your finger's skin. Your nail wasn't happy with the painful moment, and decided to retaliate by giving you a random white blob/line that stays until your nail grows out.
Other causes could be diabetes, which leads to problems with oxygenation of the fingertips, or *even worse* a fungal infection.
MDHealth.com said it might be worth mentioning your nail beds to your doctor at your next visit, but there's no cause for alarm.
"However, other problems with your nails, in addition to white nail beds, might mean that you should get attention immediately. These include fingernails that are suddenly thickening, distorting in shape, or developing raised ridges. If there is any problem with your fingernails that changes their appearance, your doctor might want to run tests to figure out what the problem is."
