I have been on 50mg Levothyroxine for a couple of years now and my symptoms are still in place: extreme tiredness, poor nail condition, low libido. The last time I went to my GP, she arranged for a Vit B12 injection and said they would be followed by more, a short course. She had my blood sampled before the B12 injection. I immediately felt better and was disappointed when I vot a text a few days later saying ‘No further action required’. When I looked at my results on the surgery website, I saw the B vit level was one point below the lowest level and a note to re-test in 3 months! I also had a Medichecks thyroid function test and the results are:
Thyroid Function THYROID STIMULATING HORMONE 3.34 mIU/L 0.27 - 4.20
FREE THYROXINE 16.9 pmol/L 12.00 - 22.00
FREE T3 4.34 pmol/L 3.10 - 6.80
a/ should I go back to my GP about the B vits
b/ Should I give Thyroid S a try?
Any advice would be gratefully received.
