Small firm lump felt on baby's rib cage. Had cold, fever. Is this lymph node?
Hi, I noticed a small firm lump (feels similar to a little lymph node) on my 4 months old son s ribcage. It is round/ oval and smaller than a pea. It is located on the left side toward the bottom of the rib cage. He had a cold with a fever recently - could this be a lymph node from this infection? Or what else could it be?
