I agree with SeasideSusie and would take her advice.
I shall give you a list of clinical symptoms and you can tick them off for your next appointment/blood test.
We are entitled to have a copy of our blood test results by Law. Always ask for a print-out from now on for your own records. If you have a query, you can post them.
Blood tests should always be at the very earliest time possible, fasting (you can drink water) and allow a gap of 24 hours from your last dose of levo and the test and take afterwards. Always take levo with one full glass of water.
In other countries if our TSH (thyroid stimulating hormone) reaches 3+ we will be given a prescription for levothyroxine (also known as T4). In the UK doctors have been directed to wait till it reaches 10.
At the next blood test ask GP to test B12, Vit D, iron, ferritin and folate and you can tell him you've taken advice from Healthunlocked Thyroiduk.org.uk. The thyroid hormones he should test are T3, T4, Free T4, Free T3 and thyroid antibodies.
He or lab may not do all of them and the ones that aren't you can have a home blood test from one of our private labs.
