<human>: Hi, I am 15 years old, weight approx 52kg and found a small pea sized lump in my armpit a few months ago. I didnt think much of it at the time however I am now beginning to worry as it has not gone away. It does not hurt or puss or anything, however It will not pop or go away.
<bot>: Hi. Thanks for your query. Read and understood that you have a small pea-sized lump in the armpit, which is there for months, and you can not pop it. It is not painful, no pus nor anything. The most probable reasons for such a lump are:Sebaceous cyst Lymph node. In a young boy of your age it is most likely to be a cyst. You may please get this confirmed by actual examination by a General Surgeon and get treated if needed. I hope this answer helps you.
