I was having extreme tiredness, backaches, unable to wake get from bed in the morning, for last 10-12 days, this suddenly got worsened in a few days that I thought something is definitely wrong. I also have difficulty concentrating, thinking, memory loss, heavy head, I checked my tsh, it was 13.7 and was started on thyronorm 25 from last 3 days. I am also taking SSRI for anxiety, but was not able to identify the cause for this severe fatigue, backaches, is it related to anxiety or depression? Or is this an effect of hypothyroidism?
