my daughter has had a blue/purple lump behind her ear for the last year we keep getting told she has been reffered to a specialist but havent heard anything at all i am getting worried now, it doesnt seem to hurt her at all but she is only two so i dont think she could tell me even if it did hurt her, everyone we have seen about this seems to pull a very concerning face however cant even give me a clue as to what it could be. any ideas? :)
