Tenderness Question?

A sympton of HIV is swollen lymph nodes of the armpit, neck and groin.  Where about is the armpit node located?  In the actual armpit?  I only ask because I have some tenderness (no pain or swelling) just below my rib cage, in the mid-section of my body, on BOTH sides.  I did some weight lifting the other day, and usually the discomfort is gone by now.  I looked at node diagrams on the internet, and could really only find them under the armpit.  Any ideas?  Muscle strain?

On both sides?  That strikes me as odd.  Are the lymph nodes actually in the "cave" of the ampit?

My guess is anxiety.  I had pain there too - mind raced that it was ARS related.  I tested negative on DUO at 3 weeks, which I am told is 90% reliable.  Either from lifting or anxiety....my guess is your are fine.
