I was diagnosed with under-active thyroid nearly 6 weeks ago. I'm new to all of this. I'm male and 60 years old. I am taking 100mcg of Levothyroxine. Next blood test - the first since taking medication is next week. My TSH was 8.48 and free T4 was 10. That's all that's mentioned on results last time relating to Thyroid. I don't know what to make of the reading and whether anyone has a view on whether dose may change. Some symptoms have disappeared/diminished but others like swelling of ankles come and go and still feel tired. I have only been dealing with GP and have thought about referral to an Endocrinologist. Is that a good thing to do? I would be good to hear from anyone either just starting out or a bit further down the road to share experiences.
