My symptoms began with exercise/sports intolerance in high school with leg pain and fatigue, vision loss. My symptoms have progressively increased to become more severe with each decade of my life. I’m 60 years old and have no life. My pain is 24/7. I cannot go anywhere without increasing pain. I had a Rheumatologist to say she felt I have an enzyme deficiency affecting my mitochondria due to my symptoms especially since I have so many drug allergies/intolerances. I had a muscle biopsy but it was inconclusive. So topic was dropped. My current GI/Liver doctor feels it is an absorption problem/enzyme deficiency. So we are back to this. I feel I fit a Long Chain Fatty Acid abnormality, Carnitine deficiency, Possibly CPT2. Since I have classic symptoms: Cardiac Arrhythmia, Muscle Pain/weakness, Collapsible fatigue, Hypoglycemia-Insulin Resistance, Vision Problems, Exercise Intolerance, Extreme heat intolerance, Endocrine Problems, Respiratory Problems, Liver Problems/Fatty Liver, Nervous System damage (neuropathy), Anesthesia Problems, Anemia.
