Today my nose stud got caught in a cotton ball and pulled almost entirely out. I managed to put it back in, but its bleeding and slightly red and swollen. I have my senior pictures tomorrow, will it be OK by tomorrow?

The redness should've gone down, you probably just tore the wound open a little more but don't worry. Try not to cover it in make up either because you don't want anything getting into the open wound. If it's the same in the morning then take some anti-inflamitories/ibuprofen to make the swelling go down. If not I'm afraid you'll have to face the other way for your photographs!
