Dont rule it out in the future mazzy, I was told for a couple of years prior to diagnosis that I was having panic attacks and depression, In the end I left it, then during a routine blood test they said I was underactive. I had blood tests at the last time when they said I had depression before but they said my thyroid was fine.
lots of people have dry heels even me, the symptoms I had of hypothyroidism was tiredness, lethargy, slow thinking, slow reactions, jitters, cold feet, finding the cold weather very difficult to cope with.excessive dandruff and flaking skin, weight gain, wirey hair ..
my doctor put all this down to depression when it was an underactive thyroid
