If the piercer hits a vein (this would be due to an error on the piercers part, lack of attention to what he/she is doing) the piercing will seep blood. This is not a good thing but much better than the piercer hitting and artery which will pump blood with little sign of it stopping. This generally require a trip to the hospital to have the piercing cauterized to stop the bleeding. So before you run into issues find a good professional piercer and do your research!!
Actually yes you can. Some people have a third vein running down the middle of their tongue and when one gets a tongue piercing it is done in the middle of the tongue. So when the needle pierces it it will bleed more than tongues w/o that third vein would. But you can still get a tongue piercing if you have that 3rd vein. All professional piercers know how to control bleeding. It's in their training
The tongue piercing done by a professional body piercer reduces the odds of striking a vein greatly, it's what we do and we know what to look for. Be sure to get this piercing done by an experienced professional body piercer and you will have no worries. Research, ask questions and check references.
All it means is that a vein has been hit. If you continue to bleed for a couple days then take it out, let it heal and try again. If it is bleeding profusely go to the ER they may need to cauterize the wound.
Generally no, there could be some complications with bleeding, but they should be controllable. You can die if the lingual artery is pierced but that's highly unlikely to happen... Infection is also another risk, but again - manageable if it happens.
Unlikely, although hitting a vein does increase the chance of an infection.
Tongues that can be pointed out of the mouth by at least 1" ~ 1 1/2" past the bottom teeth. If you can't get your tongue out that far chances are good you cant get it pierced. Over developed frenial webs under the tongue are also not acceptable for piercing.
Is it on the bottom side of your tongue? That's one of the veins that delivers blood to your tongue. The blue coloring of your vein appears purple through the pink coloring of your tongue.
Well a couple of things. 1) the tongue swelling is excessive. 2) the piercing placement is wrong and a vein has been hit. 3) you are playing with the tongue piercing too much and irritating it. Needing more information about the situation, the above should be starting points for you to consider.
lingual vein
It is called the arterial vein, and should not be punctured. Never ever pierce yourself, especially your tongue. You run the risk of irritation, infection, migration, rejection and even Hepatitis if you are not careful.
I am going to assume you did them yourself and the piercing wasn't done by a professional body piercer, there fore a vein was hit while doing the piercing. That is why it is bleeding.
No, you can not see the third vein in your tongue. But, there are 2 main purplish, sublinqual veins you can see underneath your tongue. But consider all the taste buds you have as well.
