I have severe tinnitus with hyperacusis, and I had to quit added dietary salt for various reasons. What happened when i tried adding it back into my diet was I suddenly had all the blood seem to be rushing around my head n ear area, and a much louder whooshing, tinnitus noise going on. Maybe you are getting too much salt? Try going without added salt, getting sodium naturally from the vegetable n fruit its in. People in america have way too much, salt added to everything
