Edema Chromotropic

Chromotropic edema is the dilation of blood vessels in any part of the body, which occurs under the influence of various irritants on the body (skin irritation, pain, concussion, etc.). Often accompanied by severe redness and/or swelling of the inflamed area at the site of edema. Sometimes it occurs immediately without redness or swelling. Often its cause is not clear. The “allergic” nature of inflammation (similar to Quincke’s edema) follows from its non-immune nature and the absence of antibodies that damage the cell membrane during infections and thyroiditis. It should also be distinguished from cold and venous (toxic blood stasis). Also, it can be reactive and local, often provoked by problems with the gastrointestinal tract or vertebrogenic pinching of the sciatic nerve. Additionally, there is a group of vasomotor and nodular edema - an increase in the size of the node on the surface of the skin.
