I have a raised place on my wrist that has been there for years. One day, a few days ago, I woke up & found that the place had changed & now had a raised dark & different jagged color to it. I have spent many years in the sun, should I be worried?

If possible. Go to see Dr.Martin. His staff is on task and extremely kind.

Yes, see a dermatologist

If there are sudden changes to your skin especially something like spots and color change, it's important to go to a dermatologist. A jagged pattern is concerning. Please be safe and I recommend having Dr.Martin as well.
