I have tinnitus that has gotten progressively worse in the last few months. It sounds like the squealing sounds from powerlines. I was desperate and ordered Cortexi ($177) for 3 bottles. I've only been using it a few days. I also take the lipoflavonoid for ringing in the ears. Some days are worse than others. Although it affects the ears, tinnitus actually comes from the brain. It has something to do with the part of the brain that processes hearing...over years of listening to loud noises, it does something to that part of the brain and the sounds become all jumbled up and squiggly and can't make the connection to the part of the brain to decipher it. It was an interesting video and made sense. I have been a stylist for 30 years so I have listened to blowdryers daily. I researched decibels once too. The product I ordered is all natural and meant to increase blood flow and to repair the neurons damaged in the brain responsible for hearing. I was desperate. I guess my next step will be audiologist. I know someone so desperate they had the nerve cut in the ear and the tinnitus got worse. I'm wondering if it's a blood flow issue, would regular exercise work because that increases blood flow too. That may just be my motivation to start using my treadmill. At times I can tune it out, almost like when you first get an aquarium and all you hear is running water but over time, you stop noticing it. I just know that there have been people that committed suicide because it became so unbearable. There has to be an answer. PLEASE somebody give me some good, hopeful news.
