It depends on the injury and illness. But also the nature of the skater.
I'm not a skater. I'm a cheerleader. But one time before a competition, I had the WORST backache of my life. I didn't know where it came from. Usually I don't wince if I'm in pain unless the pain in unbearable. And believe me, it hurt so much that I was trying to go into different positions and I was making faces. When we were practicing at the school where the competition was, it was hurting so much that it was hard to practice. And I had to get a bag of ice from the trainer and I had to lie down on top of it. Then we competed. I didn't focus on the pain. And once we finished out routine, the pain VANISHED. Like it went away like that *snaps fingers.*
Also I can remember another time the previous year that I was cheering at a football game (high school) and I had a sprained ankle (I actually sprained my right ankle twice and left once in a period of THREE MONTHS....) and I wasn't supposed to do any tumbling for a week. I had two days left I think of no tumbling. But I begged my heart, lungs, and liver out to my coach to let me do one round-off back handspring on the track. And she finally let me. And I felt good.
My point is, skaters have the choice sometimes. They might weigh out the pros more even if the cons stack up and tower over the pros, but athletes don't like to give up usually. I mean like, they've waited to do a competition and they don't want to not do it because they would have felt like they wasted their time waiting.
