I was diagnosed with costochondritis a couple of months ago. About a week after those symptoms started, I started to feel dizzy. I am not sure what I have or what is going on but the symptoms come and go. I am getting better but I am not sure whether I have something like labyrinthitis. Today for example, I am sort of dizzy but my main concern is the full/stuffy head sensation. I carry an enormous amount of tension in my neck and jaw so I took myself to a chiropractor who suspects this could all be muscular. All of the symptoms have been on the right side i.e. full right hear, popping right ear, slight ringing in the right ear and this is also the side that carries all of the tension. I am confused as to whether it is viral or muscular. I am studying my master s at the moment and need this to go away!
