Brief Answer:
Most probably an infected cyst.

Detailed Answer:
Hi.
Thanks for your query.
Noted the history related to your 16 year old feeling a pea sized lump under her armpit, which is tender to touch.

The probable reasons at the age of 16 are:
Infected subcutaneous cyst
Lymph node.
The commonest being a cyst as the sweat secretions at this age is more. This lump is attached to the skin hence it moves with the skin and will be attached to the skin by a punctum.

Lymph node is not that common unless there is a focus of infection in drainage area, is deep seated, does not move with skin at all and is less XXXXXXX or may be as good as fixed to the underlying area.

The treatment is:
Clean the area with plain water at least twice daily, keep it dry. Apply liquid povidone iodine to the area to make the skin sterile so that further lumps do not appear.
A small course of an antibiotic with an anti-inflammatory medicines help to resolve the condition in most of the cases.


I hope this answer helps you, please feel free to ask for further relevant queries if you need to or if you feel that there is a gap of communication.

I have what looks like to be an infected cyst on my breast. I have had it drained once about two years ago; it was not a pleasant experience. The results came back non-cancerous. It is infected again and I know it must be drained but it was no a pleasant experience. The most pain I have ever experienced. Can I try to drain it by puncturing it like a pimple? Should I be concerned and see a doctor immediately to drain it?
