Chill blain caused nail to yellow and thicken temporarily
A few months ago, I experienced throbbing pain at the outer base of my toenail. No trauma. It happened at night and the pain was substantial. There was erythema
/redness and it was sore to touch. It resolved after a couple days. Following that episode, my nail changed colour and thickened. As it's grown out, the thickened section is lifted from the remaining nail and my nail appears to be growing back as normal.
I'm wondering what the cause is? Can Chill blains change the nail? Or is it possible it wasn't a chill blain but something else?
