The child suddenly has knee pain

Children's health is the focus of every family's attention, especially children in the growth and development stage, who are prone to joint pain. This is mainly because children are growing, their bones and joints are growing rapidly, and their nutritional needs are relatively large. If the supply is not timely, calcium deficiency is likely to occur, which will cause knee pain and other conditions. So what is the reason for sudden knee pain?

Why does my child's knee hurt?

1. Growth reasons: Growing pains are a common phenomenon that causes joint pain in children, especially in children aged 3 to 8 years old. Because bones grow rapidly, while the surrounding nerves, tendons, and muscles grow relatively slowly, pulling pain will occur.

2. Hip synovitis: It is a common disease that causes knee pain in children aged 3 to 10 years old. It is common around 5 years old and is mostly unilateral, with acute hip pain or radiating to the inner thigh and knee. It is more common in boys than in girls.

3. Avascular necrosis of the femoral head: In most cases, patients will experience unexplained limping, difficulty squatting, and pain on the inner side of the knee, but no local tenderness; tenderness in the center of the affected hip, internal and external rotation of the hip may induce pain, or partial limitation of movement; in the late stage, the pain is relieved or there are no symptoms, the affected limb muscles atrophy or the lower limb shortening, and the hip joint movement is slightly limited or normal.

4. Rheumatic fever: causes pain in large joints such as ankles, knees, hips, wrists, elbows, and shoulders, that is, rheumatoid arthritis, which may be accompanied by varying degrees of joint swelling and tenderness. The pain is short-lived and sometimes subsides in just 1 to 2 days. If not controlled, it can cause rheumatic heart disease.

5. Other diseases: Other diseases that cause knee pain include allergic purpura arthritis, rheumatoid arthritis, acute hematogenous osteomyelitis, acute suppurative arthritis, traumatic fractures and dislocations, etc.

How to Prevent Knee Pain

1. Spending too much time on the sofa

Exercise strengthens the muscles around your joints and helps prevent injuries. Once your knee has had enough rest, you need to get off the couch. Swimming or Tai Chi are good choices. But don't overdo it, or your pain will get worse.

2. Slip, trip or fall

Wear good quality shoes to reduce the risk of slipping. Choose low heels with soft rubber soles. Keep your home and stairwells well-lit and clear of obstructions that could trip you.

3. Forgetting to stretch

The muscles around the knee can tighten, which can lead to painful injuries. Daily stretching exercises can prevent painful injuries and muscle aches. Ask your doctor or physical therapist about some simple moves to help you stretch while you walk or do any other activity.

4. Sleeping in the wrong posture

This can make your knee pain worse. Try different positions, and if you sleep on your side, put a pillow between your knees. Do not rest your bent knee on a pillow as this will make it more difficult to relax your leg.

If a child's knee pain is caused by accidental bumps while playing or some minor skin injuries, parents do not need to worry too much. Just give the child simple disinfection to avoid infection. If the cause is pathological, and the pain lasts for a long time and the situation is serious, parents should take their children to a regular hospital for examination and treatment in time.
