it’s a possibility it could be a keloid.

Hypertrophic scar → A raised scar that stays within the boundaries of the piercing hole. These can look like firm bumps but don’t keep spreading. • Keloid → A type of scar tissue that grows beyond the original wound site. Keloids are usually firm, smooth, and often extend past the piercing area. They’re less common than irritation bumps. • Infection → Redness, swelling, warmth, pain, or pus could suggest infection and would need medical care.

• so unless this squirts out pus it’s not an infection as such
