Abdominal pain is always characterized by cramping or discomfort in the abdominal area. It is also referred to as belly ache, tummy ache, or stomach ache. It can occur in the higher abdominal region, right below the chest, or lower region, right above the groin.
The discomfort can range from mild to severe, and can be acute or chronic. Most of the time, abdominal pain does not signify any immediate life-threatening situations. However, if the aches are recurring and accompanied by other signs and symptoms (such as bloody stool, vomit, or high fever), be sure to seek immediate medical care; it can be a sign of a more serious condition.

Causes
The presence of abdominal pain is an indicator of abnormal activity in the gut area. There are numerous causes for abdominal pain, ranging from simple indigestion to life threatening conditions. Since the liver, pancreas, gallbladder and kidneys are all in the abdominal region, the cramping may be an indicator of abnormal activity in those organs rather than the stomach and intestines themselves. Here are the more common causes of abdominal pain:
-- Severe Constipation or bowel obstruction
-- Inflammation of the gallbladder (Cholecystitis)
-- Allergic Purpura
-- Gallbladder stones
-- Inflammation of the appendix (Appendicitis)
-- Inflammation of the pancreas (pancreatitis)
-- Food allergies, such as lactose intolerance
-- Food poisoning or poisoning of the GI tract
-- Inflammation of the peritoneal lining of the stomach
-- Inflammation of abdominal lymph nodes
-- Air or gas in the digestive track
-- Indigestion
-- Irritable bowel syndrome
-- Kidney Stone
-- Stomach flu
-- Stomach ulcer
-- Tumor or cancer
etc...

Home remedy for abdominal pain
1. Ginger Root Tea
Ginger contains naturally occurring chemicals called gingerols and shogaols. These chemicals can help relax smooth muscle, such as the muscle that lines the intestinal track, and therefore relieve stomach cramps or a colicky stomach ache. Ginger root is also great for relieving nausea, which may accompany a stomachache. Sipping on some warm tea can prove very useful as a home remedy for stomach aches and is, in my opinion, more effective than ginger ale.

You will need…
-1 ginger root, 1-2 inches
-A sharp knife or peeler
-1-2 cups of water
-Honey (optional)

Directions
Wash, peel, and then grate or finely chop 1-2 inches of fresh ginger root. Bring 1-2 cups of fresh water to a boil (use less water and more ginger if you want a more concentrated drink) and add your ginger. Boil for 3 minutes and then simmer for 2 more. Remove from heat, strain, and add honey to taste. Sip slowly and relax.
 
2. Enjoy Some Mint
Fresh peppermint tea (or just peppermint tea in general) can help relax stomach muscles. It also helps improve the flow of bile, which helps you digest properly. This is especially useful if suffering from indigestion or gas/bloating.

You will need…
-A handful of fresh peppermint leaves OR 1-2 teaspoons dried
-Mug
-1 cup water

Directions
Cover the peppermint with 1 cup of boiling water, cover, and let steep for 5-10 minutes. Sip slowly while it’s still toasty warm. If using the fresh peppermint leaves, you can chew on them as well to ease stomach pains. You can also just use a pre-made teabag if you find that more desirable.

3. Rice Water
Rice water is exactly what it sounds like-the water left-over after you cook rice. It acts a demulcent, meaning a substance that relieves inflammation by forming a sort of soothing barrier over a membrane, in this case, the lining of your stomach.

You will need…
-1/2 cup of white rice
-2 cups of water
-A pot

Directions
Cook your rice with twice the amount of water you normally would for your chosen amount. In this case I am using plain old long-grain white rice. Put your rice in a pot on the stove and add the water, cooking over medium-low heat. As the rice starts to become tender, remove it from the heat and let it soak for 3 minutes with the lid on the pan. Drain and drink the water warm, adding a smidge of honey if needed. Save the rice for a bland meal later.
