Sorry that you are suffering too. Yes, I think no they are all related and effect each other. I also think that the barometric pressure effects it. Is an approaching storm, or a storm that is leaving. For me low pressure is better. Your timing in answering my post is interesting. I was getting some severe headaches and going to the neurologist for shots in my head. This usually made the tinnitus worse. My point though is in December of last year, I wound up having a heart attack. Since then I have had a few headaches, much milder than before. Nothing compared to what I used to get. I wondered if that all had to do with 2 clogged arteries. Maybe check it out, just in case (you should be concerned about that arm that gets numb). Even though I am doing better, unfortunately the tinnitus is still going strong. I wish you good luck and good health.
