I know tinnitus stems from the brain. I watched a 45 minute video on it and it's the mis communication between the ear and the brain due to constant exposure or medical issues that cause the silica in the ear to not process sound efficiently so the brain is getting mixed signals from sound it is trying to sort out. I only said I needed to see an audiologist or an ENT to make sure it isn't something else that is causing it. I've done extensive research, trust me. In fact, my neurologist also told me I could see an audiologist if I wanted to but there was nothing they could do to fix it. If it's something else like wax, something that can be fixed surgically like a growth, tumor or if it's injury to ear drum at least I'd know what was causing it. I've never had one refer me to an audiologist, it's been my idea to see one then they tell me what they think. The drainage I get every now and then that feels like sand in my ear certainly isn't coming from my brain.
