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.

I’ve not tried it but one of my old roommates got them a lot and swore by alum powder to heal them faster. It’s a cooking/baking spice that you can get at your grocery store. He’d mix it with water to make a paste and then put it in the sore a few times.
