None that I've ever heard of before. I've flown all over in the world and sometimes pretty beat up after an OP and it didn't bother me. You'll be fine.
I have a bruise on my left shin and I'm scheduled to fly from Ohio to Denver, Co next week. Are there any dangers in flying with a bruise or in such a drastic change in elevation?
A bruise isn't a medical condition, so you'll most likely be fine
