In medical parlance, swelling, turgescence or tumefaction is a transient abnormal enlargement of a body part or area not caused by proliferation of cells.1 It is caused by accumulation of fluid in tissues.2 It can occur throughout the body (generalized), or a specific part or organ can be affected (localized).2
Swelling is considered one of the five characteristics of inflammation; along with pain, heat, redness, and loss of function.
Generalized swelling, or massive edema (also called anasarca), is a common sign in severely ill people. Although slight edema may be difficult to detect to the untrained eye, especially in an overweight person, massive edema is very obvious.
Congenital swellings are present since birth, e.g., hemangioma, meningocele, etc. Some congenital swellings may not appear since birth, but later in life, e.g., branchial cyst, dermatoid cyst, thyroglossal cyst.
Inflammatory swelling: It may be either acute or chronic variety. The presentations of acute swellings are redness, local fever, pain and impairment of function of the affected organ. The related lymph nodes will be affected and will show signs of acute lymphadenitis. Chronic inflammatory swellings will show the signs of acute inflammatory swellings, but in subdued form. In this case, edema might not occur. Such swellings can be differentiated from neoplastic swellings by the fact that neoplastic swellings never recede in size, but inflammatory swellings may show occasional diminution.
Causes of generalized swelling:
Some possible causes of a swollen limb include:
While it is possible for mild swelling to go away on its own, several things can be done to relieve the symptoms or hasten the process. The RICE first aid method of rest and protecting the affected area has long been taught as a short term solution. The application of oxygen is known to assist in the reduction of swelling. An effective option for extrinsic treatment of swelling and it's reduction is Kinesio Tape (KT). By strategically cutting and placing Kinesio Tape above the area of swelling it assists in the removal of edema (swelling) by directing the exudates toward lymphatic ducts. This is aided by KT's inherent property of lifting the epidermis away from the dermis creating a larger area for blood flow and lymphatic movement.3additional citation needed
