Why does it hurt after a week of ligament sprain

Ligament sprain is a very common disease. If you are not careful when running or exercise for too long, it is very easy to cause ligament sprain. After a ligament sprain, the patient's ankles and joints will be very painful, and the ankles will generally become red, swollen, or even bruised. After a ligament sprain, you need to apply medicine or ice in time to reduce swelling, otherwise it will cause other injuries to the joint. So, why does it hurt a week after a ligament sprain?

Ligament strain. Ligaments are cords of connective tissue that connect bones to each other and run closely parallel to elastic fibers. After a ligament is sprained, there will be local swelling, pain, tenderness, and if there is subcutaneous bleeding, a cyanotic area may be seen. It is very important to treat joint ligament sprains correctly in the early stages. If it is not properly treated or misdiagnosed and turns into a chronic disease, it may leave functional impairment and be prone to re-injury in the future.

Causes and common diseases

When the human body engages in weight-bearing activities or changes body position, the muscles, ligaments, fascia, synovium, etc. are pulled. When the joints are twisted or the muscles suddenly contract, a few fibers may be broken and small joints may move slightly and become dislocated, causing a strain. Ligament strain is usually caused by external force during labor or exercise that causes joint movement beyond the normal physiological range, resulting in strain, partial rupture or complete rupture of the ligaments around the joint. This is called a joint ligament sprain. The most common areas for joint ligament sprains are the knees, finger joints and ankles.

examine

After a ligament injury, small blood vessels usually rupture and bleed, causing local pain and swelling, intratissue bleeding, hematoma, joint swelling, movement disorders, and tenderness. During physical examination, obvious pain is found in the pulling ligament. If it is completely ruptured, the stability of the joint will decrease. CT examination can be done.

Differential Diagnosis

1. Ligament rupture

Movements beyond the range of motion of the joint may cause passive stretching of the relevant ligaments, leading to tearing or complete rupture. Ligament ruptures are often accompanied by sprains and fractures.

2. Ligament sprain

Ligament sprain refers to injury to the soft tissues (such as muscles, tendons, ligaments, etc.) of the joints of the limbs or the body. The main clinical manifestations are pain and swelling at the injured site and limited joint movement. It often occurs in the waist, ankle, knee, shoulder, wrist, elbow, and hip.

3. Ligament contusion

Generally, it is because the movements during activities are beyond the range of joint movement. The degree of ligament injury is not serious, and redness and swelling will appear.

Treatment principles

1. Actively carry out early repair

In order to avoid serious functional disorders in the late stage due to lack of proper treatment in the early stage.

2. Rest

Stop exercising immediately and do not put any weight on the injured joint.

3. Cold compress

Ice or other cold compresses can help reduce pain and swelling because lowered temperatures reduce blood circulation. Apply cold compress for 15 to 20 minutes at a time, three to four times a day.

4. Oppression

Applying pressure to the injured area with a bandage or other methods can reduce bleeding and bruising. The bandage should be wrapped just tight enough to feel pressure but not so tight that the ends become numb or lack blood flow.

5. Elevate the affected limb

The main purpose of elevating the affected limb is to reduce swelling and improve blood return.
