Why would you need to repierce it if it hasn't closed? If it's too shallow or crooked, yes, close it up. You don't want the new piercing hole and the old one to meet and tear to form a single hole.
It may not need to be repierced but simply tapered to open it enough for the jewellery to be replaced. Oral piercings don't close they generally just shrink.
If your before ear piercing got infected or just closed up, and you are you getting them repierced it won't hurt at all! In fact it will hurt a lot less than your first piercing, because no piercing hole has actually closed fully, so you are piercing less skin. Like the first piercing it will feel like a pinch, but you already experienced that, so I'm sure you will be fine! Best of luck! I actually got them repierced yesterday!
It's not puss, your second piercing has bisected the first piercing and that is lymphatic matter "discharge" from the second piercing exiting our the first piercing location. Don't worry about it, it will heal up just fine just keep to your normal aftercare routine and all should be fine.
getting an ear piercing has nothing to do with a knee surgery so you should be fine.
Normal placement is 3/4" from the tip of the tongue to the top ball. If your tongue is unusually long placement can vary slightly. If you remove the piercing (no sooner than 72 hours from the time the piercing was first done) you will need to wait at least 3~4 weeks from removal date to get the piercing redone. The tongue swells and distends once it's pierced so we need to be sure this swelling is gone and the old piercing had healed up so there is no bump or distension from the old piercing to interfere with the new piercing. edit: did you know people get (not uncommon either) brain abscesses from their tongue piercings? be careful, because this is definitely one of the most dangerous areas to pierce considering how close it is to your brain stem.
A pierced belly closes quickly if you have not worn a ring consistently for about a year. If the hole closes, it may just be partially closed and it can be "punched" out again easily.
ask them how they feel about piercings before you start to ask about you getting a piercing done
Well that would be either 18g or 16g, but your professional body piercer will need to make sure the diameter is correct, which he/she will do when they lay out your piercing. This is not a DIY piercing, be aware serious dental and gun damage as well as infection and migration should be considered before getting the piercing done.
Well getting a tongue piercing should be up to you, it's your body and your decision. You need to ask yourself if it's something you want and if so are you ready to go through the healing time and the swelling and discomfort in order to get it. Oral piercings are serious piercings and should never be taken lightly, there are risks and all these need to be discussed with your professional body piercer before you commit to getting the piercing. Talk to your piercer before you decide, that's what they are there for, ask questions and get answers that make sense to you.
2-3 months before the piercing can be submerged. You can go swimming now as long as the piercing doesnt get wet.
Yes. It is just not good to drink alcohol right before getting a piercing because it thins your blood. After a piercing, drinking is absolutely fine.
More then likely they'd have you take out the nostril piercing before they pierce the septum. You should have no problem with the nose ring and septum ring getting caught on each other afterwards though.
