i just got back my ultrasound. she said it had nodules and enlarged and put me on sentroid? starting off with 25mgs. for 6 weeks, then might raise it to 50. she didnt mention anything about nodules maybe getting larger with meds, hmmm now im concerned. sometimes docs forget to give all the details, they just say this is what you have, take this pill. my sister is on sentroid as well, has been on it for years and she ended up losing alot of her weight that she had put on. but dont now if hers was enlarged nodules or i think they found hers thru blood work. my blood work came back fine, but she felt my throat area and said it felt enlarged so she sent me for a sonogram. first pill today. please let me know if any one else knows if these nodules grow during treatment.
