[@Kho] You're welcome! You're double-jointed? That might be the reason you're clicking, my father used to have severe arthritis from decades of habitually cracking his knuckles until he spent two months daily imbibing a home remedy my grandfather, (his father, not the friend of the friend who shared your troubles) recommended him, a single frozen poke salad berry a day with a shot of whisky. Poke salad berries grow in my region during the springtime, and many older folks use them to handle cramps, and joint-locks, that sort of thing. I doubt you've got arthritis in your ribcage, and I further doubt poke salad berries are common where you live, but that reminded me of it. Most home remedies are hogwash, but some really do work.
