Unfortunately it's impossible to say without being able to examine Bruno in person. A testicular tumor could swell and cause an increase in size that could resolves with an antibiotic or steroid injection. Infections like Brucella or other bacteria could cause testicular swelling. I would recommend having a veterinarian examine Bruno to determine what might be the cause.
