Piercing Problem

Amber

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Piercing problem. I’ve had my daith pierced for a while now but this bump keeps coming back and its getting rather annoying, but i clean it and soak it with saline solution. It was also pierced with titanium, so it’s not the metal. What should I do?
