question: Hi there, Im a 17 year old female and it was about 3 months ago when I got a pea sized lump under the skin in my armpit then over time it dissappeared and move to the voice box area of my neck then I got 2 on my upper arms. They have not come back since then till now. I now have the same painful lump under the left armpit and today my right breast felt the same pain and there is a small under the skin lump in the nipple area. Thinking about going to the doctors as now sure what it is.. thanks.
