I'm on too much thyroid supplementation, I presume based on these numbers, is that correctt, whomever will answer this for me, please doctor? But my subjective s/s are calling it another way. My labs generated this: TSH-0.010; T4-13.7. Meds are 175 mcgs qd, synthroid, plus cytomel-5 mcgs. bid; however, I've been on this therapy for 38 years. Is there 1. a possibility I should be changed from a synthetic; and 2. the dose lowered? Would just love some feedback.
