What is this lump behind your ear you got them pierced at 14?

The lump behind your ear is likely a keloid, which is a type of scar that forms when the skin produces too much collagen. Keloids can occur after any type of skin injury, but they are more common in people with darker skin tones. Keloids can be unsightly and itchy, and they can sometimes cause pain. In most cases, keloids are harmless and do not require treatment. However, if a keloid is causing you significant discomfort, you can talk to your doctor about treatment options. Treatment options for keloids include surgery, laser therapy, and steroid injections.
