DS (3 years old) has two lumps on his head directly behind one ear. They are hard to touch (although not sure how hard as don't want to press them too much) and just normal skin colour. He says they don't hurt and is not remotely bothered by them. Anyone had any experience of this? I've read online it could be lymph nodes - he had just had chicken pox so this would make sense. We are going to take him to the doctor but wanted to see what MN folk had to say too....
