I have similar problem but I have mine behind my left ear. It like two small bumps but their on my bone. When I went to the doctors they said it is normal and it is to do with some fluid which sometimes shows up on some people. It really annoying because sometimes realise it and ask me what it is but I don't even know what it is. Can someone please tell me a natural way of getting rid of this as the Doctor said if it bothers you, then I would have to get it surgically removed
