Ok this happens either when I push cuticles back too much, randomly happens, or if i my nervousiness i pell of top layer of nail (i know that is nasty, but just habit sorry

). Ok, well a whitish not raised bubble appears near my cuticle. If
I pick at it and make a hole, the hole gets large and reaches end of nail after a a few weeks. As it grows down to end it makes like a dip and around it the nail bubbles up raised, but is regular colored. When I rub my finger over it it is feel like different variety of bumps and smoothness. Freaks out people or makes then cringe. If
I don't pick at the white spot and open making a hole it, pretty much does the same thing. As the deep dip reaches the end of the nail, the white part of nail at end is weak and flimsy. For it to return to normal takes like month. I hope I made a clear visual and not make you cringe. But the dr. said just quit bitting and bothering my nails. He even brought a health book in the room with another dr. and couldn't diagnose it. I have tried putting stuff on my nails to stop biting and picking them, but I still do it. What I want to know is what is this condition I have, why does it make that white space that turns in deep dip and bubble up nail around it? Help please
