Dampness in the groin has both physiological and pathological factors. 1. Physiological factors: for sedentary patients, because the groin can not get sufficient heat dissipation, and here more sweat glands, will cause the secretion of sweat, resulting in a sense of humidity. Or hot weather, wearing too thick clothes, etc., will also affect the heat dissipation in the groin, which will lead to groin moisture. 2. Pathologic factors: (1) certain diseases such as prostatitis, epididymitis, etc., will lead to an increase in blood flow to the affected area, which in turn causes an increase in heat production, and even causes the scrotum to enhance the function of heat dissipation, appearing scrotal and inguinal humidity. (2) Certain skin diseases, such as eczema, can also produce symptoms of groin moisture. In daily life, you should not keep sitting for a long time, but also wear some loose fitting clothes. For patients suffering from the disease should seek timely medical examination and early treatment.
