Possible fibroadenoma, extremely painful

Hi, I posted yesterday but am still so scared today. I had an ultrasound yesterday for a painful lump in my left breast. The radiologist says he’s confident it’s a fibroadenoma but I’m getting it biopsied to be sure. I asked him if it’s normal for them to be painful, and he said not usually but sometimes around your period they can be.

Ever since I discovered this lump 3 weeks ago, it’s been very painful, regardless of where I am in my cycle. Painful when touched, painful when not touched sporadically. The pain is like a stabbing pain throughout my breast and sometimes chest, armpit and/or shoulder. I’m so nervous that this is not going to be a fibroadenoma due to the pain and because my doctor said the pain is “not normal” with fibroadenomas. Has anyone with fibroadenomas experienced a lot of pain from them? I am SO scared. I won’t know the results until next Tuesday.
