I wrote earlier-I am new to the board. My husband has for 2 years now been suffering with these symptoms off and on- they come and they go- symptoms: Tiredness, slurred speech, walking into walls, glazed confused look, pain in his joints, and many more. He has had MRI, CT scans, PET scans, every type of blood work you can name and all have been fine. His liver enzymes were very high 2 years ago, but are now normal. The doctors are treating him if he has CFS because they can't find anything else wrong with him. My question is, " is there anyone else out there that is or has experienced these episodic spells?" I don't know when they will appear and how long they will last. We are trying all the vitamins and naturally sleeping aids possible. He has even been given anti-viral medication that maybe helped. He takes herbal medication to help treat a yeast infection. Help.
