Hi, this is my first post on the forum. I have had an under active thyroid for over 20 years and I have to say my journey has been very hit and miss. To cut a long story short I've had a relapse and am struggling to cope. I'm currently signed off work, but am desperate to get back to 'normal'! I often feel that no-one understands and feel very alone (hence joining). What I'd like to know is do these relapses happen to others, even though bloods are normal? I feel worse now than when my TSH was 0.04.
