I can help you, but I need more information. Please opt for a paid consultation online with me and then send me snapshots of all your previous doctors' notes, test reports etc. The thyroid can be affected by many diseases, some infective, some autoimmune, so benign tumours, some malignant tumours, some metabolic diseases etc. It is very important for the doctor to reach an accurate diagnosis before going in for hormone replacement therapy as in some cases, the situation may rebound as in yours when you seesaw between hypothyroidism and hyperthyroidism!
