I started with a hard clavicle lump the size of a quarter.by the end of the week or so i had 5 of them.i was given an xray as well as an ultra sound.the dr told me she is baffled because they dont show up on either the xray ir ultra sound.the original lump on clavicle is now golf ball size and i have another large one in my neck on the same side.i dont know what to do but im very scared.i also think i found 4 more small ones in my groin and these lumps dont go away.its been about 6 months since i got the first one
