My husband has had mild tinnitus for years. It has slowly been getting worse recent months. He's been sick now 10 days, food poisoning morphing to veryigo. This evening tinnitus in right ear got severly worse, almost unbearable. Took 6 bismuth things last Friday ... No chronic use or overdose. What is the mechanism it causes tinnitus?
