Hi. I ve recently had a headcold but its gone now. During the cold my right ear had ringing in it on and off but now that s gone too. For the last 2 days anything that has a high frequency like my cat meowing and my grandson talking, sounds as if their voices are speaking through a fan. Now even my TV sounds like it. Its like a vibrating sound. Its making g me feel quite I ll. Do u know what this is please?
