I have recently had a total thyroidectomy for cnacer, which I have been informed was malignant. I have had four days of radioactive iodine treatment so far. Am I being self indulgent at wanting answers from people? I ask what are the chances of recurrance as it was malignant? No-one seems to be willing to give me anything close to an answer? Is it usual to feel tired even though I am on thyroxine? I feel moody and intolerant, which is the total opposite of how I usually am? Can anyone say if this is normal or if they have experienced similar things?
