I am not a doctor, but if you have no swelling, color changes or pain, I doubt that you need to make another appointment.

What you could be seeing is your body's adaptation to a circulatory problem: the creation of more blood vessels around a problem area. I think there's a scientific term for that, but I don't recall it. The first time I learned that the body could do this was with respect to a relative's internal vessel blockage. The body can create its own "bypass".
