Thanks to everyone for the feedback. The longest distance I've cycled is 3 miles, and it is a pretty flat route. I've only done it 3 or 4 times, so I don't think it is that. I did get in the pool on the 4th of July. I used sunblock on the scar, but maybe not thoroughly, not sure. I have sent the pictures to Dr's office, waiting to hear back. They haven't gotten any bigger, but they don't appear to be fading.
It seemed late in the game to get an infection, but then I remembered they want me to take antibiotic before every teeth cleaning, so I guess one could get an infection anytime.
I don't seem to have a fever, but I am concerned that it may be very mildly swollen along the incision, where the red spot is.
