I went to the ER on July 4 with pressure and roaring sounds in my head. After two CAT scans I was told it was tinnitus and that i needed to see my ENT dr. I saw him yesterday and he just happened to notice on the report that my blood pressure was high which meant that I was released with untreated high blood pressure. I am currently sitting in my physician's office for treatment. All I seemed to hear at the ER was drs order scans for quite a few patients. I found that quite interesting.
