I experienced the same, although it took longer than 5 days (I was only on half the usual starting dose).
I admit that I panicked & stopped Spiro completely for 5 weeks when I felt that my testicles were shrinking. This happened a couple of weeks after the pain started.
It took 5 weeks for my dysphoria to get to the point where I had to go back on the Spiro, although at an even lower dose. A low dose of Finasteride was also added at that point.
This was all between Jul & Sep 2013. It took until Feb 2014 to find the right balance of HRT meds.
