Children's knee pain turns out to be caused by these reasons

Knee pain is common in middle-aged and elderly people, so parents will be very worried when their children have knee pain, not knowing what causes it. In fact, rheumatic fever, rheumatoid arthritis, allergic purpura arthritis, acute suppurative arthritis, acute hip synovitis, growing pains and other causes can cause knee pain in children. Parents need to understand them one by one, treat them in time, and let their children recover as soon as possible.

1. Rheumatic fever

It can easily cause pain in large joints such as the 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 parents pay attention to it, rheumatic fever can spread to the heart and cause rheumatic heart disease.

2. Rheumatoid arthritis

Most cases occur between the ages of 4 and 10. The disease can be acute, with symptoms such as fever and joint pain; it can also be chronic. This disease can cause sudden fever and accelerate the disease progression, eventually invading joints throughout the body and causing joint deformities.

3. Henoch-Schonlein purpura arthritis

Clinically, it is common to see swelling and pain in one or more joints, and purpura on the skin. In a few cases, purpura occurs from time to time, so it is easy to be ignored. If not treated in time, it may cause kidney damage.

4. Acute septic arthritis

It is more common in infants and young children, sometimes secondary to injury or other infectious diseases. The onset is acute, with one or more joints becoming red, swollen and painful, accompanied by symptoms such as fever, irritability, and loss of appetite.

5. Acute synovitis of the hip

Most of the children are 3 to 10 years old, and often have a history of upper respiratory tract infection 2 to 3 weeks before the onset of the disease. The main symptom is mild pain in one thigh and knee joint. The pain worsens during movement and the child may limp. The disease heals on its own after 3 to 4 weeks.

6. other

Autoimmune diseases such as systemic lupus erythematosus and mixed connective tissue disease; infectious diseases such as tuberculous osteoarthritis; some malignant diseases such as leukemia are also closely related to joint pain.

7. Growing pains: Children grow very fast during this period, and can grow 7-8 cm each year. Because bones grow rapidly, while the surrounding nerves, tendons, and muscles grow relatively slowly, pulling pain will occur.

In short, children's joint pain cannot be ignored, and growing pains can only be considered after the cause of the disease is ruled out. Growing pains are mostly related to insufficient calcium intake in the diet, and the symptoms can often be relieved by calcium supplementation.
