When you have tinnitus -- or ringing in your ears -- many things can make those sounds worse. One of the most obvious is noise.
Do what you can to avoid it. Move farther away. Wear earplugs. Turn down the volume. Avoid noisy people even - friends & family aside.
Stress can also make the ringing seem louder. Find ways to relax and get it under control. If you know your blood pressure is high, get it checked often or, buy your own blood pressure monitor for home. Your doctor can help you control it.
Lack of sleep can trigger tinnitus or make it worse. Get your eight hours. Or try to.
Try cutting back on coffee or Coke / Pepsi (other Colas brands are available obviously) to see if the ringing gets better. Caffeine can also raise your blood pressure, which can bring on the ring in some people. Cut back and see if it helps.
Drinking can also boost your blood pressure, which can make you notice the ringing more. Cut back and see if that makes the ringing better.
Hope one or more of these work for you.
