[|Human|] So this Friday I came home from work and noticed that I had a small lump in my armpit (I am a 19 year old female).  I wear a tight shirt a work and sweat a fair bit there.  And I thought the pain I was feeling was the shirt rubbing.  It was when I got home I noticed the lump.I went to the ER that Saturday night because I was worried.  When I had got there the lump was almost gone.  The doctor felt what he called the remnants of it.  He said it was an auxiliary mass or something.  Well yesterday I got home from a party and noticed that the lump had returned.  Its about the size of a pea and is in my left armpit.  Its in the same exact spot the one was previously.  I am freaking out and having wicked bad anxiety.  I felt better after I saw the ER doctor but freaked out again when it came back......whats going on?
[|AI|]  Welcome to Chat Doctor. 1. The history and symptoms suggest the possible cause will be hair follicle infection / inflammation with collection, next could be lymph nodal enlargement.2. The infection can be treated with a course of antibiotics, whereas the lymph nodal enlargement will occur due town infection or inflammation anywhere in the body.3. So any illness you are aware of can be treated.4. As a remedy do not use tight shirt until complete healing, use soft clothing which will not cause the rubbing, avoid squeezing, pressing the lump - as you can complicate and disturb healing process.5. Avoid shaving, meanwhile you use trimming till complete healing - that will help.6. Apply local anti-inflammatory cream with remedies explained - should be well in a couple of days. Good luck.
