bruises
Introduction
Introduction Brucella is caused by subcutaneous hemorrhage. The skin of the human eye is thin and loose, so it is easy to bleed and gather, resulting in dark circles. The bruises initially look blue or purple-black, and then slowly fade away, turning brown. Green or yellow.
Cause
Cause
Bruise is also caused by the presence of congestion in the skin. The congestion is mostly caused by external force, which causes the subcutaneous capillaries to rupture and hemorrhage. The skin is subcutaneously caused by extravasation of blood from the rupture of the capillaries. So we can see a bruise on the intact skin. At this time, the blood under the skin caused by extravasation has been a foreign body and is rich in subcutaneous nerves. So the pain is obvious. After 24 hours of congestion, the affected area can be warmed with warm water. To promote local blood circulation and promote the dissipation of blood stasis. Generally, the body of the subcutaneous congestion will slowly absorb, and the time will take about two weeks.

It is common for girls who are prone to bruises to be whiter and thinner. Some of them will bruise when they are lightly touched. If it is clear where it is, it will not matter if it is bruised. It is caused by trauma. But unexplained bruises are not very good. If it happens occasionally, it doesn't matter, but pay attention to observation. If this is the case, it is recommended to test blood routine.
Diagnosis
Differential diagnosis
Can be differentiated from subcutaneous hematoma.
The blood in the blood vessels (usually capillaries) exudes from the blood vessels due to abnormal causes, and the mass formed in the skin is called a subcutaneous hematoma.
