That maddening sound inside the ear – like a buzzing noise – is called tinnitus and it can drive one crazy. I find it is made worse when I am tired, or when I’ve been on the phone quite a lot (mobile phones are even worse!).
Most Jin Shin Jyutsu holds or flows will help to calm the noise. However, I find that holding the ring finger is quite simple and effective way to radically subdue the tinnitus, especially just before sleep.
