If you see white fluid, then that is the white antibodies trying to fight bacteria that have invaded... like me, it is happening right now in my nail bed, it's excruciating ... due to breaking a nail down the middle of my nail bed and they having glued it with my acrylic nail set yesterday. I squeezed it and white stuff came out all over.





I hope this infection works it way out because it's killing me.
