Massaging a pulled muscle around armpit and swelled up a lymph node in top of armpit by accident. will it go back down?

lymph nodes: Often armpit lymph nodes are not an issue. When they are larger than 1cm we sometimes are concerned. I small lymph nodes very often on examinations. Or a few occasions I have found that they were associated with very serious conditions, but rarely. The answer for you is best addressed with an in-person examination, while your doctor sees the big picture. It probably not related to the message.
