...Welcome to the community! We are so glad to have you!
While we can't diagnose, we can tell you about our own experiences with similar spots and lesions. I can tell you that most of my skin cancers have been slightly itchy and appeared as dry spots that didn't heal. The only melanoma I have had was a dark and irregularly shaped mole.
I think you are doing a great job of being proactive and starting the process with your family doctor. It's always a good idea to have suspicious spots checked out. Your family doctor may even be able to do a biopsy for you. My family doctor diagnosed my melanoma with a biopsy and was able to get me into a dermatologist quickly for an excision.
I am including a link to a handy graphic -- it seems like you are already being careful and watching for many of the signs.
