Have you ever gone on a rollercoaster and got a bruise? I went to Galaxyland and went on the two rollercoasters plus some other rides. I think that when I went on the rollercoaster that went upside down and had big loops and drops I was holding on the bars. Well my arm muscle was pressed against the bar. I didn't go on that roller coaster again. It is kind of purple and right on my left muscle arm. I'm left handed. I think I leaned forward when the ride was going over a big jump plus I was held down when the roller coaster went upside down.

Is this normal? Has this ever happened to you or someone you know?

Why did this happen? The person beside me went on the same rides as me and didn't get a bruise. It was only the one arm. It feels kind of weird when I shake my arm and feels painful if I touch it.

Would it be ok if I did pushups tomorrow or would that be a bad idea? Should I stop going on rides at amusement parks or at least roller coasters or that ride?

Is there some way I can prevent bruises from roller coasters?
