Your body talks to you by sensation, and often it is a subtle language that we tend to ignore. But according to experts, there are certain warning sensations that you should pay attention to as they can be symptoms of serious disease.

“Most of the time the symptoms may not be that serious,” Dr. Gabe Mirkin, author of The Healthy Heart Miracle, tells Newsmax. “But when you have potentially life-threatening symptoms, it is better to check it out and find out you do not have an emergency, than to die because of neglect.

For example, when it comes to heart health, the American Heart Association warns that chest pain or discomfort in one or both arms can be a sign of a serious heart issue and to see a doctor right away.

Here some other potential causes for concern:

• Tearing sensation. If you feel a tearing sensation in your back, it may be caused by a torn muscle, but it could also be a sign of a ruptured aorta, according to AARP. The sensation is sudden and severe, like a knife stabbing you in the back. It’s often accompanied by nausea and requires immediate attention.
• A dull ache in the lower right side of your belly. This could signal appendicitis. Over 5% of people may suffer from an inflammation of the appendix. The symptoms can become intensely painful as time passes. Experts say that this condition requires immediate medical assistance, so go straight to the ER.
• Tingling in the extremities. If the tingling lasts for more than an hour and you are also experiencing dizziness, seek medical help, according to AARP. This may indicate circulation problems or other diseases such as anemia or diabetes.
• Dizziness. This one of the most common symptoms people report, and according to WebMD, if it is accompanied by chest pain, a really bad headache, high fever, or irregular heart rate, seek immediate help. Dizziness can also be caused by vertigo, which is not an urgent medical issue.
• Chest pain. According to the Mayo Clinic, the sensation of chest pain can be due to many causes, but should be checked out by your healthcare provider in case it is something potentially deadly. Chest pain associated with a heart attack is a crushing or searing pain that radiates down your back, to the neck, jaws, shoulders, and one or both arms.
• Swelling. Most people who have circulation problems may experience swelling in their feet or ankles which could mean that there is a blood clot blocking their veins. When too much fluid builds up in the body it is called edema, and this can lead to serious heart damage. Always investigate any type of swelling, says AARP.
