Question: 11 year girl with lump in armpit

 drniff - Thu Mar 06, 2008 8:41 am

My 11 year old daughter has a hard pea-sized lump in her lower armpit where there is a lymph node. The lump is red. Under the skin there is more swelling that radiates to about the size of a nickle. She does not shave but has recently begun to use deorderant on a regular basis. I am concerned and not sure if we should wait to see if it goes away or go to the doctor right away. She has had the lump for two full days.

User avatar Hello Drniff,

There are a few possibilities. This may be a clogged sweat gland or skin pore that has become inflamed. Less likely, it may be a lymph node. The lymph nodes in this area tend to be deeper, though.

If the area is not getting better or if it is painful I would recommend you have this checked out. There may be a small infection brewing that needs drainage or some antibiotics.

Best wishes.
