If she is not in pain, which she obviously is not playing full spreed, then she is OK. And I hate to be tough with you, but stop worrying MOM. She may have irritated it somehow to make it red again. Like Rafiki said some days will be red some not. Just be calm John. She is fine.
Thanks Man... I cannot with 100 percent say she is not in pain, but if she is, she is doing a good job covering it up and not slowing down... Trying to slow her down is difficult (as I am sure you realize).
