My 3rd post here and I'm hoping for some advice please. I've been struggling with symptoms for nearly a year. I've been on thyroxine up to 200mcg/day and was overmedicated (t3 above range) and a host of horrible symptoms. I reduced to 175 and felt immediate relief but then after a few weeks began to feel overmedicated again - nausea, palpitations, feeling like I want to get out of myself (if that makes sense). Stuck with it for 8 weeks and now have the following results from blood tests. Left a gap of 24 hours between taking the thyroxine and the blood test. After the test I stopped thyroxine for a few days and felt instantly better. Not sure what to do next, any help would be much appreciated in interpreting the below:
Serum TSH level 0.12 mu/L [0.4 - 5.5]
Serum free T4 level 19.0 pmol/L [11.0 - 26.0]
Serum free triiodothyronine level 5.2 pmol/L [3.0 - 6.0]
Serum vitamin B12 level 550 ng/L [190.0 - 910.0]
Serum ferritin level 241 ug/L [22.0 - 322.0]
Serum folate level 10.2 ng/mL [3.9 - 26.8]
Restandardisation of serum folate assay.
THYROID PEROXIDASE ANTIBODY 443 iu/mL [< 50.0]
VITAMIN D 43.5 nmol/L (Total 25-OH Vitamin D, inc D2+D3):
I'm losing hope of ever feeling better. Thanks in advance for your assistance.
PS. I've tried 150 and felt undermedicated and I've tried 175 and felt hyper. Main symptoms are afternoon headaches, tiredness in the morning and a feeling of general malaise. Strangely when on 175 I felt near perfect at week 4 then felt bad from week 5 onwards.
