I had been managing my symptoms well for the past year although I'm still very new to the long term implications and management of hypothyroidism.
In late January, I had a dose of flu'. After, I felt a bit washed out for a further week - but this is normal for me.
However, the following week, my hypo symptoms returned - it felt almost overnight. TSH test around 19 (0.35-5.5). My Gp has now raised my levo.
Is this sudden increase in TSH typical after illness and is it permanent?
