Below are my thyroid tests. I have a goiter & nodules, ultra sound shows no changes, 1 biopsy that was negative. I take Armour Thyroid 90mg, 1x a day. Doctor's say these tests are normal. The last couple years I have had problems with energy, dry skin among other symptoms and I started gaining weight earlier this year. I have gained 30lbs in 5 months despite diet and exercise. I have been on the same dose for 10 years. Anybody have suggestions to overcome lingering hypothyroid symptoms or thyroid support supplements?
