Axillary lymph nodes: ...are located in your arm pits. They are deep in the soft tissue and are generally identifiable only on deep palpation (feeling with the fingers) if they are larger than 1 cm in diameter. Nodules within the skin, that are visibly inflamed, or are very superficial, are likely to be a skin or hair follicle infection. A physical exam with an experienced physician is the best place to start.

Likely: Sounds like minimally enlarges lymph node verging on normal size. To make sure and put your mind at ease, see an MD.
