I was diagnosed with CFS/FMS in the late 1980's. For more than ten years I was incapcitated; eventually many of the symptoms became controlable except the fatigue. I still have a very limited amount of energy. Recently I had an EKG which revealed thickening of my left ventricle (hypertrophy) - I knew I had a murmur but did not know about this. When I was 10 yrs old I had scarlet fever which went into a very serious bout with rheumatic fever. My pediatrician told my parents that the murmur was a result of this disease but he never told them that it had damaged my heart valve. Now I'm wondering if it has been this damage to my heart that has caused this extreme fatigue all my life (I'm now 50). Has anyone else had a similar history?
