About.com states that an infection is characterized by a swollen, painful and warm-to-the-touch lump that may or may not ooze pus and blood. The company further explains that keloids, or excessive scar tissue growths, are generally not painful and can range in size from a very small to a large growth at the site of the body piercing. A sebaceous cyst generally is not painful, but requires treatment by a doctor for surgical removal.
Pyogenic granuloma is also characterized as a non-painful growth at the site of a body piercing, and the U.S. National Library of Medicine recommends speaking with a doctor for surgical removal and biopsy of skin tissue. About.com stresses that, in all cases, it is important to visit a doctor in order to receive an accurate diagnosis and to determine a viable treatment plan.Learn more about Piercing
