The question...: I think the system did not allow you to complete your question but I will comment based on what you could provide. Those are extremely elevated levels for TSH and can definitely make you feel sick with symptoms of extreme tiredness, fatigue, joint pain, mood swings, swelling, among others. I would assume your doctor raised the dose of the medication which you should take as px in the mornings.

Treatment needed: An elevated TSH level indicates that your body needs more thyroid hormone. Your doctor will likely adjust the dose of your thyroid replacement. Please discuss this with your doctor.

Must take thyroid: I don't know what your question is, but it appears that you were not taking Synthroid (thyroxine) for many months. This is very dangerous. Your body requires thyroid hormone to function correctly. Since you had your thyroid removed, there is no alternative to taking thyroid hormone. Having had thyroid cancer, it is essential that the TSH be normal.
