what would cause itching all over and swelling
Itching all over is an annoying sensation often caused by skin irritation or inflammation. Itching all over may be associated with a rash or other skin symptoms, or it may occur by itself. Itching all over can be caused by a relatively mild condition, such as dry skin and a build-up of dead skin cells. For example, if you feel itchy all over and you live in a dry climate, you may have âwinter itchâ caused by the lack of moisture in your skin.
Swelling occurs whenever the organs, skin, or other parts of your body enlarge. It is typically the result of inflammation or a buildup of fluid. Swelling can occur internally (within the body) or it can affect your outer skin and muscles. A range of conditions can cause swelling. Insect bites, illnesses, or injuries often result in external swelling. Internal swelling is often a side effect of medication or the result of a serious injury.
