It is dangerous to stretch this quickly because it can cause the skin to tear. You should use tapers to slowly stretch the hole to the size of the tunnel you want. You should be able to get tapers from a body piercing shop. Remember to only stretch from one gauge to the next largest, rather than skipping a size, as this can cause tears and scarring.
no it shouldn't be Stretch down a size and wait a few weeks until you stretch up again. Some people's ears turn purple instead of red when irritated but if that isn't normal for you, downsize.
I know that the hole needs to be stretched and it can be done on your own, but can you stretch just a normal piercing? Or do they do something different?
14g is normal for a male lip piercing, 16g is normal for a female lip piercing.
Unless you just got a piercing it is very normal for the earlobe to have a hot or warm feeling to it . Otherwise your ear recently was in pain or just got hit by someone or thing. The sensation of being hot and the "distention" or "hardness" in the lobe is an indication of a possible infection. Clean the piercing under warm running water and make sure there is room between the jewellery front and the backing or the stud behind the ear. If the jewellery is too tight then the backing will need to be removed or loosened to allow you to clean the piercing correctly.
14g to 16g is normal for a male lip piercing, 16g to 18g is normal for a female lip piercing.
Most piercings are pierced with a 16 gauge needle, but if you want to stretch it, I wouldn't go any larger than a 10.
Yes you can. I've had my cartilage pierced for 7 years and all I wear are regular earlobe studs. I even wear earlobe dangle earrings in my cartliage sometimes and its fine. No stretching or anything.
Swelling is normal for a new piercing.
normally it takes one-two week for piercing to get normal depending on the body's healing ..
Do you mean that the piercing hole itself has stretched? Its possible that you pulled the bar or played with it too much and it caused a tear but that seems unlikely for only having it for two days. Maybe it just seems like its stretched because the swelling has gone down a bit. Since i cant see it for myself and dont really understand what you mean by stretching, I suggest that you go and sow your piercer and have them help you out :)
No
Bleeding after getting a new piercing is normal; a piercing is technically an injury & your body will (usually) heal.
