What is the cause of an odd fingernail abnormality?

A thumbnail has a vertical gouged-out place on it about a fourth of an inch long and a sixteenth of an inch wide. It doesn't go all the way through to the skin, but it is deep and noticeable. The fingernail flattens out around it. Elsewhere on the same thumbnail, it has horizontal dips and ridges. Other fingernails are normal. For about two years these odd changes have been appearing on this thumbnail. They start at the base of the nail and gets worse at is grows.What is the cause of an odd fingernail abnormality?
It could be a case of psoriasis of the nails. Psoriasis can effect any or all parts of the body on the outside as well as inside such as the mouth.


It could also be a nail fungus that grows under the nails. I suggest seeing a dermatologist and seek his opinion on a treatment. I cant see why it would start doing this spontaneously for no reason whatsoever. There has to be some stimulus or conditon.


Hope you the best with finding out what this is and its treatment.What is the cause of an odd fingernail abnormality?
Might be a fungus. It can be treated with a pill but takes a long time to grow out.





It can happen when your fingernail breaks and then then the fungus takes hold. My father had it.





I've heard Vick's vapor rub as a home remedy.
I've heard that your finger nails are a good indication of your general health. I believe the ridges are an indication that your body isn't getting all the vitamins that it needs.





EDIT: I found this website with a list of things to look out for on your nails:
