Severe pain that comes in waves may be caused by kidney stones. Trauma to the body wall, hernias, and shingles can also cause lower abdominal pain. A hernia is a weakening of muscle or tissue that allows organs or other tissues to protrude through it.
Boiling an egg takes a while. Once the water starts to boil and the eggs are inside the boiling water, let the eggs boil for about 5 to 10 minutes. Careful, if they boil for too long, they might crack. Alternatively, bring the eggs and water to a boil. Remove from the heat, cover, and let sit for 25 minutes.
The best/only way I have found to hard cook fresh--1 or 2 day old eggs--that allows for them to be peeled cleanly, is to steam, not boil them. Put eggs in a basket over about 2 of water. Bring to a boil, cover and cook on medium heat so steam continues for about 20 minutes. Prepare an ice water bath as eggs steam. At the 20 minute mark remove basket and put basket with eggs in the ice water. Peel them in the ice water.
