TSH of 7 is out of range of most labs........ What other tests is she doing? Free T3? Free T4? No??
Get another doctor.
I second, get another doctor. I'm new to all this, but I followed up with my internist a few weeks ago after being put on levo by my obgyn with a TSH of 8.45, hair loss, hormone issues, etc and she wanted me to STOP the meds. She said my tiredness was from depression, not the fact that it's totally normal to feel worse after one's started taking the meds. Refused to test for Hashi's.
I went to the Endo on Friday who confirmed everything I've been thinking and reading was correct, she adjusted my meds, did a sonogram of my neck, will test for Hashi's. She actually listened to me.
