What do you need to go through in order to get a tongue piercing? There was a slight issue in my case and I really want to get the piercing. When I went to get the piercing the guy told me he would not be able to do it as there was a problem with the vein in my tongue. Do think these things matter, because if they do not then I would go through with the piercing. He said the piercing would have to go through a vein and would cause problems.
