11. Chest Pain
Believe it or not, there are over 30 reasons why you might be suffering from chest pain, and very few of them mean anything good. While experiencing chest pain may be something as simple as heartburn, it can also spell a heart attack.
Don’t push through the pain and take the risk. If you are experiencing shortness of breath, fatigue, cold sweats, irregular or fast pulse, or you’re even concerned about the pain, visit an emergency department.
