Debating if I should go into work in a few hours even though I feel like crap!?

I have been coughing like crazy for the past 2-3 days. Got worst yesterday while at work to the point that i could barely talk. And to top it off I'm cramping like theirs no tomorrow. 
Do you know what, my job will be fine. I would think they would rather me stay home and not cough on the other employees and especially the customers.
