DTOTT, I am glad that you found this board. Please keep us updated and it is a good thing that the doctor has scheduled an ultrasound. But, why not a mammo too? Don't worry and research your symptoms. The more you know the more questions you can ask and the more power you have to be, as Deb stated, your best advocate.
Two are better than one, because they have a good return for their work: if one falls down, his friend can help him up. Ecclesiastes 4:9-10
