When I bend my fingers upward, it feels as if the bottom of the finger is being stretched like a rubber band. At this point I can see a space between the dead, white
nail and the nail-bed that is clear.
I would like to know if this is a condition all its own, and if so what it is called. I know that I will be able to treat it by simply forcing myself to break this compulsive habit, but if there is anything that could restore the health to my nails, please suggest it.
