I quit taking testosterone 3 weeks ago - having issues

Quit taking testosterone, my last injection was Nov 11th. Now I can’t hardly walk half of the time. My quads and only my quads are super weak feeling and I have fallen twice. Normally when I wake up they feel fine, then throughout the day they get worse. Tonight I fell in the parking lot and my wife had to help me back up. Anybody have any suggestions? Or ever heard of this?
