Guidelines for treatment

Hi,

Does anyone know what the official guidelines are for treatment? I have read somewhere that GP's like TSH to be above 10, and I struggle to comprehend that many dont diagnpse on symptoms. My GP is so dismissive of my symptoms (tiredness, achey, dizzy, brain fog, always cold, dry skin and hair etc).

In Jan I was tested and

TSH was 6.5 miu/L (0.25 - (5.0)

fT4 17.5 pmol/L (9.0 - 23.0)

TPO antibody came back as borderline no range listed but measured 257 iu/mL.

I have just had another blood test which showed my

TSH had dropped slighly to 6.10 miu/L and

fT4 level was 15.2 pmol/L both same ranges as Jan.

I plan to ask for a trial of thyroxine but really think my GP will be dismissive, last time I visited she said thyroid couldn't possibly account for all my sypmtoms and wanted to diagnose fibromyalgia.

I feel I need to go in ith some proper research to hand, preferably guidelines, I have looked on the NICE website but cant see anything listed for thyroid.

If anyone has any ideas or advice it woulbe very gratefully received.

Thanks for your help.

Aries.
