ask for a more complete thyroid test. TSH alone can be normal when other levels can be off. My TSH is normal...i have many hypothyroid symptoms. My natropath suggested that i have a T3, T4, Free T4, antiTPO done also. Turns out my thyroid is not functioning because my body is attacking it. Ask for more tests and inform yourself. there is a great book out called Living Well With Hypothyroid...what your doctor may not tell you. Understanding is so important. Good luck.
