I read that some people don't get healthy till they have passed about 2-3000 stones and that more can form in just a few days. And I may be wrong but doesn't the liver have tens of thousands of ducts? I was thinking that I read somewhere between 30,000 and 50,000. If it has that many ducts then 2000 stones somehow doesn't seem like such a huge number.
As to the swollen hand. That can be a result of many things. Alergy, which has alread been mentioned. Heart problems, pinched nerves or even parasites can also cause your hand to swell. My husband went to a doc for swollen limbs and they were never able to figure out why. Eventually it cleared up on it's own. I think you are on the right track trying to find your own health solutions. But if the swelling continues despite your best efforts then it's time to seek a more traditional medical opinion.
