Antibodies are high. Doc changed my levo to ndt (on my request) and I feel so bad. Thyroid sore and swollen, very weak, depressed, no energy. Was on 150 mcg levo, now taking 2 grains thyroid s split in two doses. Should I go back to levo or push through this. Been on thyroid s now for 3 weeks. Started with 1 grain but couldn't get out of bed, felt so drained. Upped gradually to 2 grains. still feeling weak and tired. No energy. Please someone advise.
