Ahhh, another doctor that's willing to pump you full of testosterone but doesn't manage your estrogen that inevitably comes trodding along with it. AI's are used to prevent your body from creating excess estradiol from what it feels to be an overabundance of testosterone. This is done by the production of the aromatase enzyme (hence Aromatase inhibitor (AI) = Aromatase Inhibitor) which just happens to reside mostly in your fat stores. Excess estradiol (E2) can make you feel just as bad as low T as it increases blood pressure and many other nasty side effects. I would strongly suggest you get that measured with a simple blood test and see if your doc (unlikely) is willing to supplement with an AI.
A word of caution: Many docs will think that they need to lower testosterone dosages as estradiol climbs, which may or may not be in your best interests. If you feel he is not sufficiently educated in the treatment of your hormone situation, it may be a good idea to start shopping for a new doctor.
