Levoxyl and memory problems

my hair has been falling out since on levoxyl. i am also having muscle fatigue (mostly in my legs) and memory problems. the memory problems are slight, such as in conversation i lose the word that i am trying to think of. (this happens often)

After taking Levoxyl, I am no longer fatigued, decreased vegetative symptoms of depression that go with lethargy, however, I came to this site as I have noticed memory problems, despite all other symptoms being relieved from Hashimoto's Thyroiditis.

I have Hashimoto's thyroiditis. Since I started taking Levoxyl I am no longer fatigued or cold. My TSH levels stay between 2 and 3. However, I seem to be having memory problems that are getting worse. Also I have pain in my hands and feet and sometimes wrists and ankles. I have been tested for everything in the world and they have found nothing. I did not have this pain before the levoxyl, so I assume it is a side effect.
