I've had those itches on Testoviron (any test will) - for a few a minutes a day on the upper body the entire cycle, especially around the shoulders and upper back. Imagine the problem being compounded by not being able to reach the back or shoulders to scratch unless you can find a wall. When the itch starts you want to pound the walls, break the doors down, and put anyone around you through the windows. Even my endocrinologist was aware of this problem.
