I guess I should clarify my comments. Regarding your question of whom you should see, I would first see an OB/GYN rather than a GP because they are more familiar with the issues with breast changes. I wouldn't recommend going to a dermatologist since the problem my not be dermatological at all. If you don't have an OB/GYN, then a GP or an Internist should be able to help. My first choice would be to see the OB/GYN doc.
wow that was helpful -n0t
Start with either a GP or an OB/GYN. Let them guide you to your next steps.
Best of luck!
