What could two red splotches on right breast (after injury) be? (20 year old silicone implants).

I fell on our wet bathroom floor and hit my right breast on the edge of the granite counter as I fell 3 weeks ago. (Implants are 20 years old, silicone). There was a little soreness and light bruising but otherwise okay, very sore for a week then I forgot all about it . I just noticed two red splotches at the points of the worst hit part of the breast (far right side) It is a little sore, no itching, no fever. What could these red splotches be?
