my dad has had chronic back fatigue for about 7 years now. It can upset his stomach at times and he feels weak. He also has vertigo with it. He has a hard time concentrating. He has been to a rheumatologist, orthopedic sugeon, neurosurgeon, spine clinic, pain management, ENT, and a nephrologist. I dont know what else to try. Every Dr. says he is fine. Is there a place that will evaluate him with different dr s? I will take him anywhere!
