A member asked:

I have a knot under my armpit... i believe is from my breasts hematoma. is that normal?

A doctor has provided 1 answer

Not typically normal: Breast hematoma implies a blood collection or bruising either after surgery or some trauma. Have you had any of it recently ? More commonly a knot in armpit is either from a simple cyst or lymph node or infected hair follicle.
