Basically what is wrong with my nails now is that they have ridges that run vertically down the nail bed, and some have very prominent, bumpy knobs or ridges
down the center of each nail
. I can file these down, but then the nail
becomes very red, thin and painful. My dermatologist showed me pictures from a nail textbook of the advanced stages of this disease, in which the cuticle grows all the way up the center of the nailbed, splitting the nail in two.
