Hello, over a year ago now I got a scaffolding piercing in my ear, and never had any problems and it healed very well, but recently and I mean like over the last few days a small lump that is barely noticeable has come up upon the root of the helix and is causing me mild pain, but once pressure is put on it, it becomes quite painful I don't know why this is and wether it is linked to my piercing but don't know what to do about it and weather it's worth seeing a doctor.
