My father has parathyroidism due to vitamin D deficiency ...which is now getting cured . However since some time back, he says he feels shivering cold(winters are going on though) inspite of putting on woolens ,also he has burning sensation simultaneously.Moreover , he also has lower back ache ,and weakness in legs ,so much so that he basically has to lie down and rest.I wanted to know if these are the symptoms of hyper/hypo thyroidism .Also the possible reason why these symptoms are there.Would be grateful if doctors and others could please help me out...
Thanks so much in advance.
