Way too often, illness appears out of nowhere: for example, you wake up at night with intense stomach pain. Or you stumble while carrying something heavy, and can't get through the day without pain.
Stomach pain is an extremely common problem, but most often it is easy to deal with. Your doctor can recommend a product to relieve the pain. The most common cause is gastroenteritis - a viral infection of the stomach, which your immune system can fight on its own, in addition to taking proper medicine.
Severe stomach pain that makes you feel very ill (it can also cause fever or chills) could be due to a more serious condition or food poisoning. If you experience any of these symptoms, you should visit your doctor to receive treatment.
If you have agonizing pain in any area of your belly, seek immediate medical help. It may be a sign of a serious illness, for example, appendicitis, that will only get worse without treatment.
