Should a scar be the same redness even after seven months? im not 100% sure it is a scar, but that is what my doctor said. should i be worried?

It can be: If the scar is abnormal you can have redness for a long time.

Diagnosis first: Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
