I am new to this board, but not to CFS and its symptoms. My daughter, now 20, has been ill for the past 6 years. Dizziness is one of her major problems. She often faints. A cardiologist diagnosed her with neurally mediated hypotension after a positive tilt table test. NMH is very common with CFS patients. When my daughter's brain fog is at its worst so are her dizzy spells and fainting episodes. She has to crawl up stairs and can barely walk without help.
Before she was ill, she was an extremely athletic girl...tennis player, runner...she used to perform jump rope tricks, flipping through the air... the crowd of people screaming and clapping. Now, she can barely get out of the house. It is unbelievable.
