About 3 years ago I had my over-active thyroid gland treated with radio iodine. I am now, of course, underactive and take 150 mcg of Levothyroxine per day.
I have been otherwise healthy but just lately I have been struck with severe stiffness in hips and thighs and have also been suffering from pains in my arms and legs. I am a 68 year old male and have always been healthy and active.
Are there any Thyroid related conditions which may account for this very swift turn of events?
