No idea.................But one day a couple of months ago I accidentally took two days worth of my BP medicines and my tinnitus decreased dramatically..........My BP was 112/65.....................

My tinnitus came on like hitting a switch. Full blown instantly. I was awake for over 75 hours before the hospital put me under. My doc and I tried all the sleeping potions which gave me either nightmares, hallucinations, or such a restless sleep it was worse than no sleep.
I found Dr. Phau’s program which actually helps. He has a 2% full cure rate ( not me) but a large & of people who it helps (me).
It takes some getting used to, but if you stick with it, it really helps.
OHSU, top NW hospital’s tinnitus clinic, told me I had one of the worst cases they had seen, recommended specialized hearing aids to help mask and put the sounds into the background. Did, went to Widex, best thing I ever did, $3k to 7K, MINE COST $6,500 AND AS MY WIF3E SAID, “WE WOULD HAVE PAID $50K” Web cost will half that but then you don’t have access to a good audiologist. Need help? contact me! Be glad to help.
