With my last blood test, my TSH was 4,5 (0,2-4,9) and my free T4 17,9 (9-20,6). I know these my levels are within range, but doesn't TSH seem quite high?
I started B12 injections 5,5 weeks ago (1 injection/week, so already got 5 injections) and my main symptom was anxiety. This anxiety is almost gone, but I have such a depressing feeling, almost all day long, and I didn't have this before injections.
I wonder if this can have something to do with my thyroid? Do the injections affect your thyroid?
