i have all the symptoms of hypothyroidism ... severe fatigue, hair loss, weight gain, feeling of an aching lump in my throat, brittle hair and nails, decreased sense of smell and losing my voice. Blood tests showed a TSH of 3.4 and a throat scan showed nothing despite my gp seeing a goitre. Vitamin D levels were very low and i was given supplements but the symptoms still persist. A further blood test also showed a TSH of 3.2. i have enlarged glands under my jaw and very aching throat but no redness or discolouration...please help
