I think you should see your doctor first. Don't rule out anything. Don't tell him/her what you have or don't have. Just tell the symptoms. Then after he/she diagnoses then tell them what you think. My tinnitis was definitely not buzzing but it was worse when I laid down. I had tinnitis for over 5 years. Finally, one day I woke up and realized that I don't have it anymore. When I forget and I take high doses of pain reliever, I get ringing for a week or so. I had tinnitis from taking high doses of pain relievers to offset sore joints from taking a certain medicine. Visit your doctor for an exam.
