My TSH was 0.019 a month ago and now is 0.005 even though I have been taking 60mg x day of Methimazole. Is it dangerous to have such a low TSH value?
I have been taking also Propanolol to lower my pulse because I was having tachycardia.
My symptoms are: extreme sweating especially when I wake up, fatigue, muscle weakness (arms and legs), dizziness, nausea, blurred vision (sometimes double vision), edema in my feet.
Current values / month ago values / normal range
T4 Thyroxine 12.6 / 21.3 (4.8 - 13.9)
Total T3 187 / 296 (60-181)
Free T3 5.7 / 9.2 (2.2 - 4.0)
Free T4 1.80 / 3.18 (0.76 - 1.46)
TSH 0.005 / 0.019 (0.358-4.700)
My TPO a month ago was extremely elevated (6500) but endocrinologist didn't give me any medication for it. It has been elevated for the past 2 years but never this high (values were between 1000 and 3000 before).
I am a woman in my early 40's and have been having thyroid changes (ups and downs) for the last 8 years.
I am scheduled for a MRI of the brain with contrast next Monday to follow up on a meningioma but I'm worried the contrast will make my thyroid condition worse. Should I cancel the MRI?
I will appreciate your comments. Thanks!
