<s>[INST] Hello doctor, I got my lab results recently. I have an appointment with the thyroid doctor in a week. I am afraid of going to the ER plus I have muscle spasms, body jerks, and confusion. Two days ago, I took a double levothyroxine dose of 125 mcg. Yesterday, I added 5 mcg synthetic T3, maybe a second dose later today. So, is this okay until I can get to a doctor? Is it bad to do double levothyroxine? Of note, I am a no-thyroid. I had Grave's and was on RAI some 26 years ago. Hypothyroidism is apparently co-morbid with undiagnosed neuro but is a known trigger for tetany-like spasms, claw hand, grimacing, body jerks, startle but normocalcemic and no hyperventilation. The labs are TSH 11.47 high, total T3 55 low, free T3 1.99 low, free T4 0.85 borderline low, total T4 6.7 in range. T3U, RT3, TPO, Free Thyroxine Index (FTI), and antibody results are pending. Ferritin 53, Folate 5.75, Vitamin D 22. Strangely, cholesterol suddenly is very high when it is usually low (same diet/stress/exercise as usual). B12 at 1069 makes me wonder about the liver. Before seeing these lab results, I was going to check liver and kidneys for other reasons. Please help me with what to do for just a few days. Many thanks. [/INST] Hello.
