Hi, for the past week or so ive been having some strange symptoms, in my left year only there will be a ringing sound then it goes blocked, and like i can no longer hear from it this lasts for a few minutes then goes back to normal. Then also i ve been getting super strong stabbing pains in the left side of my head, which last for a few mins/secs and then goes away. Also the other day my both my hands started trembling, for a few minutes then stopped, all of this has not been happening at the same time but mostly the sharp pains in my head they happen daily. and its so painful that when they happen it feels like it could knock me over or something..
