It’s been 3 week since I last saw the dermatologist
How long ago did you go to the dermatologist? How long has it been since it started hurting? If notice changes (even in sensitivity) to a mole, it's worth giving the dermatologist a call- much better for them to tell you that everything is fine, rather then not take action on something that could be an issue. Let us know if you are able to call them and how you are doing!
