Anyone know what causes dimples in the fingernail bed?

Is there any chance that you also have patches of skin that are really, really rough, possibly scaly, very itchy at times?

It is possible that this is psoriasis. It won't kill you, don't worry. But if you do also have skin problems similar to what I've described above, please see your doctor and ask for a referral to a dermatologist (skin doctor).

You have a nail fungi. Along with ridges or dimples there are probably a slight discolor in the nail itself. These are usually treatable with a once a day cream applied to the nail itself. There are also pills you can take that do the same thing only faster & better, however, it's also very expensive. The cream & the pill have to be prescribed by a Doctor There are a few over the counter products but they done anything for me , ever. Hope this helps.

The attachment of human muscles to skin is what causes dimples.

gotta say never heard of it..anyone in your family have it? and do you drink a lot of milk or not? i know milk causes calcium deposits beneath the bed of the nails. other than that im clueless

Why are you pulling a terrified cat from the bed you weirdo. The cat wants to stay there.

My doctor told me it was lack of calcium.
