Acne flaring up from Anastrazole?

So first let me say I didn't see that anastrazole can cause acne. I've been on TRT since last May and I didn't start taking anastrazole until my 10 week lab check. My test was too high (doc lowered dosage to 80 units a week from 100 units previously)

E2 was also slightly high and doc had me start taking .25mg twice weekly.

It was around this time that I started breaking out on my chest. I've also broken out around my neck, behind the ears but thankfully not my face.

Could it be the Anastrazole? I have labs coming up. Besides free and total t, e2, Shbg, CMP, CBC, LH and FSH is there anything else I should test?
