Is the common joint pain side effect of aromatase inhibitors an indirect result of lower estrogen, or is there another pathway involved in which the AIs are directly affecting the joints themselves?

I am asking this because I am a competitive armwrestler and joint health is of upmost importance. I am about to start a cycle of between 750-1000mg test/week with 225 deca/week. No orals. I have never run test that high before as all my other cycles only consist of 375/week of test (with tren) at most. I have never had to worry about aromatase inhibitors before and I want to make sure I don't get much bloat or water retention from the test because I am a weight class athlete and need to keep my weight in check. My last blood test showed I had a 109 estro level, which was much higher than expected.

I would like to run aromasin to keep my estrogen in check but not if it leads to even minimal joint pain or aches. Am I able to run an ai to keep my estro somewhere between 30ish and 80ish and NOT have any joint pain? I worry about the joint pain but I don't want added water weight from the estrogen either. Perhaps trial and error to find a balance? Any help would be much appreciated.
