3. Redness
Areas of the body that become inflamed might appear to have a red color. The reason for this is because the blood vessels of the infected areas are filling with more blood than there would typically be. The red areas are usually located where the inflammation occurs. For those who have arthritis, they may notice redness around their joints. If you are suffering from another ailment, you might see red areas located throughout your skin.
This may be the body merely trying to fight off an infection of some type. Red areas on the skin can also be a sign of an allergic reaction. If you notice that you have red areas on your skin and you start to have difficulty breathing, it is vital to seek medical attention right away as there is a good chance that you have an allergic reaction that could be deadly if not treated as soon as possible.
