I am getting results of blood tests tomorrow regarding Hypothyroidism. I have been monitored for several years as borderline - this was picked up in routine blood tests. In the last few weeks I have experienced tiredness like I have never felt before and tendon pain in my hands, arms and legs - particularly my ankles when going up and down stairs. Can things change so quickly? It may sound stupid but I hope the results are conclusive and I can start on medication - just want to feel normal again. Is this common? Thanks.
