I have been diagnosed as borderline hyperthyroid and put on 25mcg levothyroxine 5 weeks ago and told to have blood retested in 3 months. Have had hypo symptoms since October'12. Have not felt any improvement since taking Levothyroxine and since 2 weeks ago my thyroid on left hand side has been enlarged and it feels like something is stuck in my throat. Went back to dr today to see if they can increase Levo. Dr took blood to test for antibodies and I am to have a scan on my thyroid and told to wait and see the results of that. I would appreciate help in understanding my blood results which were taken on 12 Feb'12 to understand why I am borderline if I am feeling so awful.
