Pain is a natural response of the body that alerts one of potential harm or injury. While some types of pain are normal and can be easily treated with natural or holistic home remedies, there are certain types of pain that may be severe or persistent. These pains may be signs or causes of underlying health conditions that require immediate medical attention. Certain types of pain that one should never ignore are listed below. Chest pain Chest pain can indicate a heart attack or angina- a form of chest pain triggered by reduced blood flow to the heart. Chest pain can also indicate other severe conditions, such as a pulmonary embolism or aortic dissection. Severe headache    Common causes of headaches include dehydration, lack of sleep, eye strain, or sinus infection. But when one experiences a severe or sudden headache or headaches accompanied by other symptoms like a stiff neck, vision changes, dizziness, or tingling on one side of the body, it may be a warning sign of underlying health concerns. Usually, severe headaches may result from a head injury, the onset of stroke, meningitis, low blood sugar, or more. Abdominal pain    Abdominal pain can indicate various health conditions like appendicitis, ulcerative colitis, or a kidney stone.
