Hello... This may be nothing, buy my husband (healthy 71) just brought to my attention a lump that is at the top of his thigh just under the crease of his torso and opposite his scrotum. It is about 3/4 long and 1/2 wide, dark purple/brown, it is quite solid and just under the surface of the skin, does not collapse as a vein would with pressure, and doesn t move freely. It causes no pain. Is this something we should have checked out or wait a week or so to see if it changes? Thank you, XXXX
