If you are suffering from tinnitus, make sure to avoid loud noises. If possible, keep a pair of earplugs on hand with you or stick your fingers in your ears. Sticking cotton balls in your ear is also a viable option if you don't have or don't wish to purchase earplugs. Loud noise makes tinnitus much worse; try to stay away from loud instruments or parties altogether.
You should try to go and get your blood pressure checked. Anything from hypertension to other stresses that increase your blood pressure could cause tinnitus to become louder in your ear. If your blood pressure is elevated, try to do things to alleviate it. You should possibly consider taking blood-pressure medication, reducing your caffeine consumption, or just learning different stress management techniques.
If your tinnitus is getting you down you should instead focus on what's great about your life. Write a list of everything you love, enjoy doing, or are happy you are involved in. This will perk up your spirits and help you to get over the misery tinnitus can bring.
The state of your mouth could actually affect the severity of your tinnitus. Make sure you get all dental issues taken care of and ensure you don't have temporomandibular joint disorder as either of those can make your symptoms far worse or even create the problem altogether when you don't have tinnitus at all!
If your doctor tells you there is nothing you can do about your tinnitus so "just live with it", it's time to get a new doctor! There are new techniques and strategies being created all the time on ways to help you deal with the sound in your head, from coping mechanisms to therapy.
Only try homeopathic remedies with the supervision of your doctor. Any supplements you decide to take should be recommended by a medical professional, not an unlicensed person, such as a relative or friend.
