I've had these ridges on my fingernails for as long as I can remember but they seem to be getting worse and now a "mottled peeling" of skin on some of my fingers has appeared. I've had chronic pain for years (with the attendent medications), have sleep apnea/no-slow-wave-sleep, and am a paraplegic from a cancerous tumor on my spinal cord when a child. But other than that am in perfect health. Does anyone have any idea what this is, especially the nails? They split all the way to the cuticle sometimes and as soon as any "white" appears they start splitting so I have to cut them. Thank you so much
