I know tinnitus affects each of us differently, but I notice how variable my tinnitus is from day to day and I wondered whether others experience this. My T usually is high-pitched, but some days it's a lower pitch. Sometimes the noise clearly is focused in my left ear, other times I can't place where it's coming from. Yesterday, the volume was low; today, it seems to be louder. I have no idea what causes the changes in pitch and volume. I've gotten a referral to an ENT (no appointment yet), but I'm cautiously hopeful that they'll be able to identify a cause and provide treatment, but I know that it's possible they won't find a thing. I recently did one of the online hearing tests; it tested your hearing against background noise. My husband did much worse than me; he got a 74, and I got a 94. It was no surprise to him since he's aware of his hearing loss. Luckily, he does not have tinnitus in spite of his hearing loss.
