Hollie, interesting that you are asking for clinical advice but on your other thread, asking whether we are professionally qualified to do so! Once again, you'd get better replies if you'd posted this in the Health section under Body and Soul - but don't repost now... You say that the doctors are "uninterested and unhelpful" - well, you have two options - insist on a referral to an ENT Consultant, or change your GP, which you can do freely these days. If the doctor admits to a wrong diagnosis, surely they haven't stopped investigating for a root cause?
