Hello and welcome to the forum. We’re not docs here, just fellow patients, but here are a couple of thoughts…
1. Is your doc testing Free T4 and T3 in addition to TSH? Since you are currently symptomatic, a TSH test alone might not tell the full story.
2. It would be worth it to get a complete physical to rule out the possibility of any other medical conditions that might be contributing to your symptoms. You deserve to feel well again — so you definitely want a doctor on your team who will work with you to get to the bottom of these symptoms.
Take care — and keep us posted on how you are doing!
