My fingernails have always been a little weird (I was born missing the fingernail on my left index finger)

I noticed that since my left hand went numb, my fingernails feel really weird (I know that the numbness is what's making the nails feel weird), and they seem to break a heck of a lot easier than they used to. The nails on my right hand seem to be ok tho. Altho the nails on both hands seem to be becoming a little flakey (pieces flake off the end of the nails.)

I am having problems with hangnails on the left hand. Seem to have more of those since the numbness started.
