I'm very scared. Two weeks ago I went in for my annual mammogram. This morning I woke up with an ache under my arm. I felt around and my lymph nodes are swollen very large. Later that morning, the mammogram placed called and said there was something new on my film and I would need to come in for an ultrasound. Having to go back for the ultrasound does not worry me so much as this has been a common occurence for my mother, but having the swollen lymph nodes in conjuction with getting called back, does worry me. Any info would be appreciated.
