I have a lump on my right underarm. It has been here since around Feb 2014 when I had swollen lymph nodes and fever. I was also 3months pregnant that time. I didn't think too much about about it since the pain went away and it didn't really bother me much. It doesn't cause discomfort but I'm just wondering why the lump is still here. I am a generally healthy 23-yr-old mom. History of Asthma (my mom), Diabetes (dad's side), and high blood pressure. I was a very active athlete back at teenage years. Now I exercise occasionally, around 2-3x/week. Height is 5ft 1in. Weight is 119.4lbs.
