I have been trying since 1974 to find diagnosis for symptoms of fatigue, mental forgetfulness. I did treatment for lyme disease, chronic Epstein Barr, cytomegaloris. Have gone to Mayo clinic, Emory in Atlanta, Shands Clinic, and no one ever looked at thyroid. I took gamma goblin IM for 25 years and for awhile it decreased symptoms. I believe after years of chasing a diagnosis is Hashimotos.
