Extreme pain and redness: I had my chin implant surgery a little over a year ago.

I will get some random swelling and pain from time to time on either side but for two weeks straight I have had excruciating pain on one side. I can feel a large lump on the edge of the implant and it almost feels like the edge isn't laying flush with my bone anymore. And now there appears to be a red mark kind of spidering out from the lump. Is this an infection of some sort or has my implant just moved? Will it heal on its own?
