I have a 6 month old baby boy, Since birth he has been perfectly healthy. One day I had discoverd a lump behind his ear and then I realised or "thought'' it was those little round bump's everyone has behind there ear's .. until today, I was rubbing his head when I realised that it had moved instead of being behind his lower/mid behind his ear it had moved to behind the TOP of his ear and where it had been before there is his normal little round bump that everyone has there, So i believe that this lump was on TOP of that little normal round bump and that is why i believed it to be nothing. Now this lump wich has moved up is not rock hard but not soft, kind of in the middle and when you touch it , its mobile, it moves around wherever you touch it very easily.. It is about 3 time's the size of the little round normal bump he has ( that we all have ) so i would say its about the size of a nickle.. Im so very scared and desperate for answer's. I plan to take him to the hospital immidiatly tomorrow morning but in the mean time ive been trying to research and figure out an idea of what the lump could be.. please please give me any answer's or suggestion's/ idea's you may have, anything will help. thank you SO much. - Josie. Btw my email is ' YYYY@YYYY " if needed. thanks.
