I want you to get a Free T3 and Free T4 test done. You could have secondary hypothyroidism which is where the pituitary is also mildly dysfunctional and is not sending the signals properly. The pituitary is where the TSH is coming from while the T3 and T4 levels are actual thyroid hormones.
When my TSH is 2.2, I feel sick. I feel best with it about 0.5-1.5.
If you can't get your dr. to test you go to
http://www.healthcheckusa.com/ and sign up to get the VIP Profile Plus II. Use code 12345 to get a discount. (It's an easy code to remember for us with brain fog, lol.) You pay something like $75 with the discount to get tests done with TSH, Free T4 and Free T3. You can then post your results here along with the lab ranges, and show them to your doctor and demand treatment if you need it.
