Go to a different school. Or you get a lip retainer from your local professional body piercing studio.
depends on what your facial structure looks like
Get a retainer. You can use acrylic but I think glass works best. It wont completely hide it but its better than nothing. You can find them online but look around at your local piercing shops first :)
No, the hole will grow in in a matter of hours. You can order a hider to make it look like you don't have a piercing in your lip.
Red swollen hot may or may not have blisters
Yes, a left lip piercing would look good with a Medusa. I have my Medusa, Snakebites, Septum, Right Nostril, etc... If anything, get more! :-)
No, but you can buy a retainer which will make it less noticeable.
If it is absolutely necessary go to your piercer and ask about a glass retainer. You really shouldn't change it and it will still be visible with a glass retainer. The swelling may be obvious too.
For your upper lip, Left is a monroe piercing. The bottom lip could just be a lip piercing, or labret piercing.
