The pain can occur in any situation: while standing; while lying down; and sometimes while I am sitting. If it happens while standing, I can usually get relief by sitting.
The swelling, or pea-sized lumps, were not at the site of the previous hernia, but rather along the cord on the underside of the muscle, right above the scrotal sack.
There is tenderness at the bottom of the hernia-repair scar about an inch to the right and above the base of the penis, but only when you press in. That is not, however, where the cordal pain I am describing, occurs. I should also mention that the hernia repair was done with the use of mesh. The intermittent pain I am experiencing began before the hernia repair was performed but was not isolated as a separate pain at the time.
