Blood Tests - Tender Breasts

Hello,
I have been on 180mg TstE / E5D for 6 months now.
and 10mg Tamox morning and night for 2 weeks due to breast tenderness.
A month and half ago I had gyno surgery, what I had for almost 5 years.
I feel like the tamox isn’t working for me, and I’m a little scared about it.

Weight 95kg, height 185cm, 12-14% BF

thank you for any advice

Why is that? Your gyno is returning?
