"Suspected stroke"

In April 2008 I started bouts of vertigo. Weeks later I was taken to hospital with a suspected stroke. I was given a heart scan, chest x-rays and a brain scan twice. I was given very little information by the doctors. As of today I am no nearer a cause or treatment for my problem. However, I thought the porters, cleaning and catering staff and the nurses are great, but above that my confidence with the treatment is nil.
