<s>[INST] My granddaughter has an almond shaped lump behind her left ear. She is behaving normally- running around happy and crazy (she is 23months old). All thing appear normal except this weird lump. It s mostly solid but (my daughter says squishy) I didn t want to apply pressure. [/INST] Hi, welcome to Hcm,Lump behind ear can mean a lot of things but good thing is that she is otherwise has no complaints and so that normally doesn't need any evaluation . however, better be safe than worry and get it checked by a pediatric surgeon only to rule out any swelling that needs removal. In my opinion the description seems like a lymph node which can be normal. Take care. </s>
