Chin Implant Infection from aggressive massage? Possible? (Photo)

4 years ago, I had a chin implant placed. 5 months ago, I aggressively massaged the implant, thinking the right side was higher than the left. This led to swelling, and since then, I've noticed a total of 3 small red spots on my chin. They lasted about a week, starting tender and then being just red, about the size of a large pimple, without gland. I also felt tightening in my chin a month after the massage. Could my massage have caused an infection? If so, how can I confirm if it is?
