I've cammed through 3 kidney stones at once (kinda regret camming through that pain, but it was in my first few weeks, and my exhusband had just quit work), colds, flues, bronchitis, and fevers. Normally, as long as I don't have nausea or am in severe pain, I'll get on cam. I definitely agree it's harder to maintain game-face, especially since you go in knowing these will likely be slow days, but making bills does have to happen. Plus it can be nice/helpful being somewhat distracted from how bleh you feel through caring member friends.
