i banged it on my bed this morning. should i stop doing massages until it's better? i have no idea what to do.

I think it would be better not to massage just untill the inflammation and soreness abide. When the bruise turns greenish (if you got one), you can continue, as that's when the inner trauma has already started to heal.

thanks. there's no bruise luckily but it's still a little sore.
