I am a 66 years old woman and had a total Thyroidectomy in July and am currently taking 75 mcg of Levrothyroxine. This is the first month of taking a reduction from 100mcg to 75mcg and am being monitored by my GP each month until I am stablised. I have been reading a lot of information on this site and Thyroid UK site as recommended, but still feel confused about the relationship between the THS and T4 in the blood test results and what it is actually indicating.
The latest blood test results taken at the beginning of October show: TSH - 0.11 mU/L within the range (0.35-4.94) and T4 (thryoxine free) - 14.50 ng/L within the range (7.00-14.80). My GP said that the T4 was too much and the TSH was not enough and the trick is to get the balance right. I am not sure what the "right balance" is? I know that it is not right at the moment.
With the change, I feel a little better overall but I still do not feel right - ie the vertigo has lessened considerably. This has much improved as the vertigo was happening much of the day and at night when sitting, laying down and walking was a nightmare as it felt as if I was going to pass out. Now, most of the day the vertigo is gone but I still do not feel able to drive as occasionally if I do turn my head quickly by brain spins. The numbness in my right leg has virtually disappeared too.
However, I seem to be swinging from having loads of energy, feeling so good, positive attitude, clearer thinking, no aches or pains, but being able to sleep very little and the least little noise disturbs me. The other extreme is the complete opposite and horrible. The shift can happen very swiftly and without warning from one state to the other, noticing that shift from positive to negative can happen swiftly if I am stressed by something. The two extreme states are difficult to cope with.
I do have confidence in my doctor but I would like to have a little more understanding of what the results mean so that I can ask any relevant questions when I have the next blood test at the beginning of next week.
ps. I must add that the result ranges are that of the french medical system and may be different to that of the UK ranges.
