Be careful with bruises on the skin
Whenever people see a bruise on their skin, they often think of it as a fall or a bump. In fact, there are many other reasons that lead to this condition.
Knees and thighs turn purple for no reason
While bathing her 10-year-old daughter, Ms. Ha in Binh Duong discovered two bruises on her child's knees and thighs, with a purple center and a light pink halo. When her mother asked, her child denied that she had fallen or hit anything. Despite the bruises, when her mother pressed on them, she did not hear her child cry out in pain. To be more careful, the next day she took her child to school and confided in her teacher, who confirmed that her child had been playing happily with friends for the past few days.
Seeing that her child was not in pain, she felt at ease leaving her at home and did not take her for any medical examination. After monitoring her for a few days, she saw the bruise gradually fade and disappear about a week later. Some time later, she accidentally discovered a painless purple mark on her daughter's thigh.
This time, she decided to take her child to the doctor to find out the cause. The doctor said that the child was lacking some vitamins such as B12, C, etc., causing the body to not produce enough platelets or the platelets could not perform their role, leading to subcutaneous bleeding.

Subcutaneous hemorrhage is a common phenomenon that occurs naturally due to lack of vitamins, folic acid, etc., but it is also necessary to be on guard against cases where these painless, non-itchy bruises are a sign of dangerous diseases such as polycythemia vera, cirrhosis, etc.
Ms. Hong Loan, 32 years old, in Ba Dinh, Hanoi, often saw bruises on her arms, legs, thighs and neck without any clear cause. Seeing many people like that and they recovered after only a week, she did not pay attention. Thinking that she was anemic, she supplemented iron and changed her diet to increase blood, but the situation did not improve.
In recent months, the bruises were not only on her limbs but also spread all over her body, accompanied by symptoms of dizziness, headache, tinnitus, blurred vision, fever at night, irregular menstruation, etc. After going to the hospital for examination and testing, the doctor concluded that she had polycythemia vera and needed early treatment.
Do not ignore skin bruises
When injured, small blood vessels will rupture, blood will escape, accumulate under the skin and form a bruise or subcutaneous hemorrhage.
Doctor Le Thi Phuong Hue, Thanh Nhan General Hospital said that skin bruising has many causes. Usually, skin bruising due to collision will go away on its own after a few days. The bruise can be small or large depending on the level of damage to the blood vessels. Usually after 2-5 days, these bruises will change color from dark red to blue and then yellow and slowly disappear. For mild bruises, minor injuries, just use ice immediately after falling, hitting the edge of a table, slipping down the stairs, after surgery, etc. to help the blood vessels contract, reducing inflammation, swelling, and bleeding.
Bruising on the skin can simply be a result of damage to the vascular wall after trauma, but it can also be caused by disorders of the blood clotting process such as a decrease in the number or quality of platelets, disorders of blood clotting factors, or acquired vascular wall damage. Due to vitamin deficiency, medication, maternal genetics, etc. When the body does not produce enough platelets or platelets do not perform their role, even without injury, subcutaneous bleeding is very likely to occur.
In particular, in some cases, bruising can be a sign of a serious illness. Therefore, to know the exact cause of the bruise, a blood test is needed to see if the platelet count is normal.
The people most susceptible to bruising are women, the elderly and children. Bruises are often concentrated in the thighs and upper arms because the skin is thinner and therefore more susceptible to damage.
Doctors advise that although most bruises are benign, they should not be ignored. When they see a bruise under the skin, many people often ignore it and do not seek treatment. With normal bruises, they can be red-purple, slightly painful and will go away on their own after a while.
However, if you see many bruises under the skin for no apparent reason or the bruises that have dissolved then keep recurring frequently, you should go to the hospital immediately to have your blood checked because there may be diseases that need to be identified and treated by a doctor.
