Should I call out again?

Hey y’all so I have either some kind of bacterial or viral infection. It started Thursday, my throat swelled up and because of that I can’t really eat anything solid without being in pain. Even eating yogurt and mashed potatoes is uncomfortable for me. I started taking antibiotics the other day but no change (it’s still early though). Throughout the day it feels better and other times it feels worse. It doesn’t hurt too bad when I’m not eating or drinking just feels like there’s something in my throat. I’m not sure if I’m contagious or not or what it is that I have. I could go to work but I really don’t feel the best and want to be able to leave early if I need to but due to being short staffed that may not be an option if I go.
