I have all the symptoms
of hypothyroidism, but my labs show normal ranges for TSH, T4, T3, etc. Some of the major symptoms are extreme fatigue, weight gain, puffiness or swollen hands and feet, feeling cold, hair loss, constipation, memory lapses, unexplained joint pain and irregular heatbeat. I have also been diagnosed with an enlarged thyroid, but a recent sono came back normal. Is is possible to have hypothyroidism and still have blood test within normal ranges?
