Tears can happen to healed or freshly stretched piercings. Tears don't randomly just happen, it usually means something has happened for it to tear. If your ear is bleeding more than a pins head worth, its more than likely you have torn it.
Stretching to large stretching to soon catching it something jewellery issue (maybe the flare was to big or to sharp)
If you have badly torn your piercing while stretching, it is suggested to put your current size back in rather than the new size to help the ear heal with less scar tissue. Tearing can lead to issues when wanting to stretch up again. Issues from tears: Scar tissue making it harder to stretch Blowout Rejection of jewellery (piercings like navel, eyebrow, nipples ect) Snapping of tissue (lobe piercings)
Blowout is one of the most common issues with stretching piercings. Especially lobes. Blowout is most commonly caused from stretching to quickly but can be caused from other issues. These things include reactions from bad jewellery, jewellery that is poorly designed, trying to fit in jewellery that has a very large flare. It could even come up from sleeping badly on your piercing while wearing jewellery (thats usually only for lobes).
Blowout takes the form of a 'lip' that forms on the outside of the fistula (the piercing hole). This is tissue from the inside of the piercing being pushed out of the fistula. If not dealt with quickly, this issue can become permanent. If you think you have blowout, go see your piercer ASAP and it is not suggested to continue stretching the piercing until the issue is resolved and then waiting 1-2 months before stretching up.
Blowout is most commonly seen when stretching with tapers as it is easier to skip sizes with tapers.
Downsizing is the best solution to blowout and let the ear reabsorb the tissue. More information in the 'general information' section on downsizing.
Some people are born with allergies to some materials but for others it can slowly build up over time until one day a reaction occurs. The most common metal allergy is nickle but things like acrylic can also cause problems for some. Wearing jewellery made of titanium, glass or organic matter will help keep those ears healthy.
Other things may include getting chemicals into the fistula (like hair bleach, hair dye), knocking / catching the area or even just cleaning it with the wrong cleaning solution.
If your ear is red, angry, swollen and leaking any sort of fluid Modify suggests just taking the jewellery out and leaving it out. While putting a smaller size plug in may keep it at a larger size, the ear will heal quicker if there is nothing in the fistula at all.
