Hi.. I would not suggest you to wait for another week to get to a doctor. It could be a pus collection behing the ear or worse could be infection in the ear itself. Since it is bump is increasing in size, better get to know what it is as early as possible...
thank you just got back from the docters i went up there and sat till they saw me. it was a swellen lymp node and she gave me antibiodics and antinflamitory and a pain med and to me give it till the antibodics are done and if it is not any better to came back for a reforal to a ENT for a byopsie.
