Pain is subjective. Yes you will feel a pinch just like any other piercing. Lip piercings are commonly rated at 4/10.

Swelling is a normal part of healing. Initial jewelry is intentionally longer to allow room for swelling before downsizing later.

Flat back labret posts are the standard, hence the name. Hoops can be used in some lip piercings but once they are fully healed.

Absolutely yes! Lip piercings swell a lot, we must leave room to accommodate for that. once the swelling has gone down we strongly recommend you come in to downsize. Do not play with the jewelry. This can cause damage to your teeth and gums.
