you will need to have this hard fixed lump properly examined. an axillary lymph node is certainly a possibility and hard fixed nodes are concerning. sebaceous cysts can also mimic nodes.
hard lump in my armpit? . i've noticed for about a month now that in my left armpit when i push down about 1cm i have a hard bump that doesn't move (assuming it's a lymph node). are you supposed to feel anything in your armpits at all? it does not hurt at all when i push on it.
