Usually the T's will run high with a low TSH --- without you posting any lab numbers I can only assume you may be hyperthyroid. Normal protacol to treat this your physician will Rx Thyroid medication. I am sure your doctor has looked over the tests and will decide what treatment is best. I would call your physician and see exactly what your condition is and ask on how he/she is willing to treat this.
I do not have experience in your area of ? but wanted to say Hello & Welcome! I am not too familiar with how the T3 and T4 come into play .. I am hoping others may jump in to offer advice!
