I think I am dying...please help.?

I'm all too familiar with incompetent doctors! The symptoms you have mentioned sound like those of hypothyroidism. Are you taking thyroid replacement hormone pills, such as Levothryoxine, since the removal of your thyroid? Have you had your thyroid level checked lately to see if you are on the right dosage? Are you seeing an Endocrinologist or Oncologist? I don't know why a doctor won't order you a CT scan. Keep going to doctors until you find one that will be more sympathetic and compionate. I am sorry that you have been through so much, and that you live in chronic pain. Are you taking anything for pain? I hope you can find a doctor that will help alleviate your fears and anxiety. Good luck and best wishes!
