The jewellery for piercings isn't something you buy off the shelf, the piercing needs to be measured and size according to what you were pierced with and where the piercing is at with the healing. You need to see a professional body piercer to get the appropriate jewellery for your piercing.
you should use a stud
Generally the size is 18g~16g for female lip piercing, this depends on the jewellery type and style desired. 16g~14g for male lip piercing, this can again vary depending on the style and design of the jewellery.
No, it is not recommended to clean a lip piercing with hydrogen peroxide as it can be too harsh and irritating. It may slow down the healing process and can also damage the delicate tissues around the piercing. It's better to use a gentle saline solution or a cleaning solution recommended by your piercer.
You should not self-pierce your lip as it requires proper technique, proper equipment, and also you need to keep everything sanitary. But if you have already done this by yourself then I would say that you can use ice because using ice is considered the best method for healing lip piercing. You can place an ice pack directly on the swollen area for some time and repeat this for a couple of times to get rid of the swelling. If you are facing any kind of major issue then you must consult a professional without wasting any time.
Can I use Orajel before I get snakebite piercings?
Well the hard lump is due to the cleaning product you are using (more about that later). If you get down to your local piercing studio, the piercer can use an insertion taper to reopen the piercing and replace the ring. Yes the lump can be fixed by ceasing the use of whatever aftercare product you are using, irrigate the piercing twice a day with just water (in the shower works fine) dry the piercing and don't apply anything else to the piercing for a week (7 day period). The lump is a reaction called a hypertrophic reaction, this is a reaction to an irritant (in this case the healing agent you are using). Rinsing the piercing with water while rotating the ring will flush this out and the piercing will resume healing.
yeah but its probably not the best thing to do.
you can use coco butter
You can massage it to promote healing. Vitamin E oil is good to use for a massage. Or you could just massage it dry. Only use the vitamin E on the outside though.
Go see a professional body piercer, don't screw around with your piercing if you have no clue as to what you are doing.
Just get a long lip stud. The piercer should've put that in to begin with.
