Feeling uncomfortable when taking a meal. This sign pops up not that frequently, but it’s still worthy of paying attention. Many people feel that cramping pain in the chest when having their lunch, dinner, supper, or whatever. It is better to consult your personal health care provider to find possible solutions to this discomfort. What we can say is that it’s time to eat healthier food like boiled, soft meals instead of fried food like French fries or grill. It is also important to control oxygen levels.
