I usually wear clear or nude nail polish but I took it off a few days ago as otherwise my nails get a bit discoloured if I don't give them a break.
I was quite shocked to see they are two toned, and after some Googling, it appears to be what is called Terrys nails.... 
Has anyone had this before. I don't know if its something underlying that warrants me rushing off to a doctor, or if its something that just comes and goes.
My first thought was that I had used one of the Scholl nail buffers things a few weeks back, and after that my nails did feel a bit sensitive.
If so you have this, could you just share if you know what caused it please.
