Like many areas of the body, your mouth is teeming with bacteria â most of them harmless. Normally the body's natural defenses and good oral health care, such as daily brushing and flossing, can keep these bacteria under control.
Moreover, stomach and digestive symptoms (pain, shooting pain, radiating pain, pressure, fullness, tightness, discomfort) also can be felt in the chest area and may be perceived as heart related, as well. Stomach and digestive symptoms are also common for stress and anxiety, and can emulate chest tightness, pressure, and pain.
What causes pains in chest muscles?   Answer     It could be a number of reasons. Pain in the ribbed area of the chest is called angina. Extremely severe pains in the chest towards the upper-center â¦and/or upper-left areas can mean a heart attack.     Localized pain more near the stomach area could merely be signs of gas or indegestion.
