I am very stressed over bad ringing in my ears, I have lost some hearing in one ear, and over the last few months have had some dizzy episodes, not really had bad headaches or vomiting, still working etc, but feel so weird, really loud ringing and funny sensation in my head, I have seen dr a while back and they said I might need an mri, but I have a dental bridge so was concerned about the metal in my mouth, any ideas
