On my left breast i have starting the corner of my armpit to right above the aerola there is a good 4 + inch chord/rope like potruding thing that has hard pebble like knots attached to it..its almost like a piece of yarn that get those tight double knots in it..it really protrudes..and sometimes painful! ive seen my dr. and he said its unusual and hes pretty sure its not a varicose vein, but brushed it off saying i need not worry about it. just keep an eye on it. Anyone experience this, should i insist on further testing other than a clinical exam? stresses me out..what is it!?!?!?
