im 35 years old and have total tyroidectomy last january 19,2007. since march 2007, i often experience short breath, (luck of oxygen) my muscle is trembling, my joints specially in arms feel so weak. my doctor advise me to take tyrax everyday (lifetime) and calcium caltrate twice a day lunch time and before bed time. i have soooooo.... many questions, apprehensions, and soooo afraid of what is happening to my body (changes of how i felt in my entire body) sometimes i had a morbid thought that will i die?my purpose of having surgery is to remove the mumps in my neck because it is getting bigger and i want to extend my life for my kids because i have told that it is associated with hearth disease if not removed. but now sometimes i want to regret my decision. also i've read that too much calcium intake can affect my kidney.please response immediately i really need to clear my mind. thanks
