I am currently reeling from one, and I don’t understand where this little white dot came from and why it can cause so much pain.

Lack of sleep causes them for me. I don’t know if its because my immune system is screaming at me to go to bed or what but I’ve consistently gotten them when laking proper sleep for several days.
