Recently I keep getting a strange sensation in my head. It sound like a shuffling sound or as if something is being shaking in my head. sounds the same as opening a fizzy drinks bottle. It only last a few seconds at a time, but it makes me feel slightly off balance. it happens if I am tired or in a lot of pain. And can last all evening. Even if I lie down and move it still happens. I was off work on annual leave and I rested all week until Friday when my husband and I went shopping, in the evening I was tired and the head started. It is do strange. I don't want to go to my GP. he will start to think I am a hypocondriac ( is that how it's spelt)
Any one suffers with the same problem,or any ideas what it could be?
