Sixteen months ago, I went to bed and woke up with the most extreme dizziness. Everything was bouncing and I couldn't walk or lift my head off the pillow without vomiting. It carried on until I ended up in A&E the following day. CT scan was clear. I had anti sickness and fluids and eventually the sickness stopped. Since then, my world has not been the same. Walking is unpleasant as I feel constantly slightly dizzy and unbalanced. Everything I look at when I'm walking moves slightly. Going up and down the stairs feels a bit hazardous and I have to concentrate. Postural vertigo tests are clear. Vestibular neuritis may be the cause apparently but an MRI scan on my left ear showed nothing abnormal. I've been given exercises to do but it's exactly the same as it was the day after it happened. I feel like I have no energy. I'm wondering whether to go for a private MRI scan of my whole brain. Hospital have just left it that there's nothing they can find so that's that but I'm miserable and also worried that it might happen again but even worse.
