i recently aquired tinnituss and am now getting lightheaded and some nausia, been through every test givin on heart, brain, circulatory, all is good, was in the hospital for 2 days this week, they r saying that it is tension headaches or migranes, headaches seem better but ear ringing and lightheadedness is worse, feels like slight pressure in the ear and ringing got a little louder, i do have accute sinuitis on the left side and that is the ear thats ringing. whats your thoughts??
