I have a dark spot on my lip on the left side and I have very small freckle like ones on the right side, both being more on the inside of my lips. I also have em inside my upper lip above the cheek area. This developed maybe about a month ago. I have researched what it can possibly b and I believe it was due to high caffeine intake over the winter where I was drinking tea at 1 to 3 times daily which I've never done before. I went to the doctor, and I was told it seemed harmless like a pigment discoloration. I went to the dermatologist today and I was asked if I have excessive dryness and pain which I don't. She said it doesn't seem like any kind of skin cancer but to b safe she took a very small sample of the affected area to test. I will call her next week but I wanted to get some more opinions, I do feel alil uneasy. Any thoughts?
