Hi jewles63, I just read your message and I relate to you and your symptoms. I had my thyroid Iodine treatment in 1984 and now I do not have a thyroid gland at all. I also take levothyroxine prescribed to me by an Endocrinologist. She has upped my dose recently as my thyroid is too low and my parathyroid is far too high. I do have a cyst on my parathyroid gland. She also took me off taking Calcium tablets every day. I too, also get the shakes through my whole body and no Dr. has ever told me what this could possibly be. I almost fall all the time, so I stay home a lot. I am not sure if I have ever told the specialist. Perhaps she would help with this problem. I am going to call her. I also want to tell you that for about five years I suffered so much pain in my chest that I couldn't breathe properly. I saw many specialists including having many heart tests done, Holter monitor, treadmill test done while laying on a bed with dye. I forget now what this is called. It takes hours to do it and I have had it done twice. I have been told that my heart is fine and that perhaps I have Costochondritis. After so many years of suffering, I cried to my Dr. and told her that I couldn't stand the pain any longer and she gave me a script for Amitriptyline, and guess what? My pain has totally gone away. I take two pills at bedtime and no more pain. It is truly a blessing for me. I am not sure if you have the same type of pain as I do, but it was always in my chest where my breastbone is. I stopped going anywhere because of this pain. Now I have Bursitis in my shoulders and am in so much pain every day. Getting older sucks big time.
