Got mine in the early nineties, was doing fine until a couple of days later when my car died in the middle of an intersection in a small village nearby and I had to push it out of the road.
By the time I got a ride home, all the wedding tackle was doubled in size and the dependents had turned a deadish black and blue throughout (all with a very deep ache and nauseated sensation in the mid-abdomen like a UFC fighter had given me a groin kick).
Doubling up on undershorts or wearing a jockstrap along with frequent sit downs on ice with feet elevated helped resolve the issue reasonably quickly.
Moral: When they say no heavy exertion, lifting, or strenuous activity, they are speaking in your best interests- but you gotta do what you gotta do....
Just don't do what my neighbors did and have unprotected sex before the labs prove the efficacy of your V- (both he and she were RN's and shoulda known better), hence their 6th kid, little surprise that he was.
