I TOTALLY understand! I have a cold right now...stuffy nose, pressure in me head, watery eyes, and cough...no fever. I contemplated same thing, if I should confess. Luckily I'm 8 days out But I do work the next 6 outta 7 of em on 12 hr graveyard shifts...so rest is not much of an option considering I also have 2 small children! But I'm praying and trying to do my best to rest up and kick this thing. I'm doing what you are...doing my best to kick the cooty booty and seeing where I'm at day before...
I suggest not hiding it if it were even possible. Its just to risky. Recovery sounds like it can be rough so why make it a gaurantee painful recovery or turn from cold to worse cuz of infection.
Hope you feel better!
