Hi, I found a small lump on my daughters right side when she was a few months old, it was soft and squishy, I had it looked at and was told it was something to do with lymp something or other, it disappeared with her growth, but now nearly 3 it has come back with advengince, it's big and more hard than before, it has a blue ting and causes her pain, I am awaiting a referral, 4 weeks so far, and even in that time it has grew! Aim very concerned, we fly out in a week for a holiday abroad, is it even safe to do this?
