I think my incision is still a pinkish color-- assuming you're talking about the color of new skin, it's normal. (If you mean bright pink and it's hot to the touch, that's bad).
Also, my incision is still desensitized- for some people, the nerves never heal and it's always like that.
Now, if it is actually tender like it is sensitive or hurts, I would go get that checked out.
