Washington was named after the first U.S. President, George Washington. The D.C. stands for District of Columbia, a special area created that is not a state. At first, it was made up of a piece from Virginia south of the Potomac River and a piece from Maryland north of the Potomac River.
Chest pain can be caused by a strained or pulled muscle, a pinched nerve or an inflamed tendon. An injured rib can also cause pain that is difficult to localize. Shingles is a viral infection that may begin as a burning sensation on the chest, torso or back before lesions appear.
Chest pain may be caused by poor blood flow to the heart leading to angina, or by a sudden blockage in the coronary arteries resulting in a heart attack. Other causes of chest pain can include indigestion, reflux, muscle strain, inflammation in the rib joints near the breastbone, and herpes zoster or shingles.
