I talked to my doctor on Thursday when she called to tell me that my results were fine. I asked her if the lymph nodes are supposed to show up on the scans and explained that I was concerned since I have had melanoma already. She basically said it isn't abnormal so she isn't concerned, but that if I am still feeling the pain to come see her again before Christmas. I felt a lot better after talking to her, and each of these emails and letters I get (email and letter each from the doctor and radiologist, for both the mammogram and ultrasound), I feel less blown off.
I haven't been assigned an appointment yet, but I go back in December for my 3 month skin check with my dermatologist, so I will be sure that she knows that this was going on, and if it is still bothering me, find out what her thoughts are too.
