I can assure you that I was crawling along a beach in agony for an extended amount of time. I cut out a couple of bits, but essentially I went from crawling - to trying to rub it out in the open on a reclining plastic chair - to trying to rub it out in a walkway (people around caused issues obviously). The whole route was over half a mile. Anyways, point being, there is zero exaggeration in the story.
