I have had armpit and side breast pain on the left side for about 3 weeks now, and last week I noticed it is quite swollen. It hasn't gone down and luckily I had a doctor's appt today. She has referred me for an ultrasound next week. She didn't feel any specific lumps or lymph nodes, but it's just very puffy and swollen in general- and tender. She said it could be hormones, but we do have a history of breast cancer in the family, so better to be safe than sorry. I just know I am going to be a big ball of anxiety until this ultrasound!! Has anyone had anything similar to this? I am so nervous.
