Can you feel the tip of the nose stud through the swelling?

Nostril piercing done by a professional body piercer should have no swelling due to the method and technique used to do the piercing. A nostril piercing done with a piercing gun (which is in contravention of most health regulations and guidelines) will have swelling and is not an acceptable means or method to pierce a nostril (generally the placement is incorrect and the jewellery is not designed to be used in that manner).
