The number one, most important thing for you is to find a good thyroid doctor. By that I mean one that will treat you clinically by testing and adjusting the biologically active thyroid hormone levels, Free T3 and Free T4, as necessary to relieve symptoms, without being constrained by resultant TSH levels. Symptom relief should be all important, not just test results, and especially not TSH. Many of our members say that symptom relief required Free T3 to be in the upper third of its reference range and Free T4 to be around the middle of its range.
If you will post your thyroid related test results and reference ranges shown on the lab report, members will be glad to assess the adequacy of your testing and treatment.
Some of us do much better on name brand meds. Is your Dr checking all of your levels? TSH, FT3, FT4 and antibodies? We also have a wonderful Thyroid forum here at Medhelp. I would post this same question there too. The people are extremely knowledgeable about everything thyroid related.
