I'm in need of the collective wisdom of MN.
My dd has just come to me with a sore/painful lump on her head - it's about a cm across, is behind her ear, and on examination under a bright light, is not red, swollen or an insect bite.
She told me that she first discovered it yesterday, and that it was smaller then but still 'sore'.
I've drawn a line around the outside, and am leaning towards her getting it looked at, especially if it gets any bigger.
Anyone have any idea at all what this could be??
