I took my six year old daughter to the doc about a month ago because of a lump on the left side of her head near her ear. The doc prescribed antibiotics--which my daughter completed, and the lump is still there. Because the lump was still present, we did blood work, but nothing was found. Six weeks later, my daughter still has the lump on the left side of her head, and now a smaller lump has appeared on the right side of her head.
