Ah, just looked ip your profile and you take 100 of levo.... In that case, wouldnt expect to see t3 at top of the range, with free t4 only just above bottom.... I would be looking to investigate rt3/ t3 ratio. You will probably have to go private though... Genova or blue horizon....
If you don't feel well then meds aren't working as they should.
High//low cortisol could affect ALL meds and should be addressed as could be your answer.
I think galathea's suggestion of RT3 could be right as this could block the T3 receptors blocking T3 from reaching the cells and giving hypothyroid symptoms.
Addressing cortisol issues, and nutrient & iron deficiencies and medicating on T3 (which you are) should clear excess RT3.

Well, i'm not so sure about the rt3 issue if you are on t3. Worth getting it tested alongside your free t3 so you can at least rule it out. So thats free t3, rt3
Then there is always the trusty saliva adrenal test.... Just to rule that out too.... I felt awful, despite t3 and this was only resolved once i saw the results of the saliva test.
And the usual suspects... D3. B12. Iron and ferritin.
You looking at about £300 for getting that lot tested.... I put mine all on my credit card and paid it back once i was able to work.

However, I feel it only worth getting RT3 tested if you have someone to interpret the result for you.
There are complicated ratios to be worked out, whilst considering symptoms, sex hormones and other when evaluating RT3 and elevated RT3 isn't always bad as it depends on T4 & T3 levels.
If this were me I would spend the money on sups known to help conversion and gut health so aiding good thyroid hormone synthesis. Depending on age and monthly cycles, I would also get sex hormones tested as oestrogen dominence can impair thyroid function.
Anything that impairs good thyroid function could be the cause of high RT3.
