Nolvadex (tamoxifin) does not decrease testosterone from aromatizing to estrogen - it merely binds to tissue in your breast and decreases your odds of gyno. Now high estrogen is not necessarily a bad thing, BUT you do have to consider several things:
1. How do you feel? Are you anxious, emotional, scared, aggressive, or moody?
2. What is your blood pressure? With that level of estrogen, a good amount of folks would have high blood pressure. It it is high, you need to get that down asap.
3. Your test is a little high. If your doc used lab corp, then the range is <1100 so he should lower your dose which will decrease estrogen.
4. How is your cholesterol? Sometimes a dose like that can screw with lipids which over time will cause damage to blood vessels.
5. How are your kidneys? If you bp is high, this is hard on kidneys.
6. How is your rbc? It it's high, go give blood, take 81mg of aspirin in the morning everyday, and drink at least a gallon of water every day.
If you still have estrogen problems after your test is lowered and your lipids aren't poor (if they are, you DEFIANTLY don't need an aromatase inhibitor like arimidex), he should prescribe an ai. After he does, be sure to get bloods done frequently. Never take an ai blindly.
If your doc told you that nolvadex will lower your estrogen, fire him and get a new one. That's basic stuff.
