My sixth-grade son's pain behind his knee and in the calf hasn't improved. ㅠㅠ

Ten days ago, my little one was walking down the school corridor unaware that friends had spilled water, and suddenly his leg tore open and he sat down. That day, he called saying his groin was hurting, so we went to the hospital immediately. The hospital said there was no major issue, and it seemed like his muscles were tense, so they recommended anti-inflammatory medication and physical therapy. We have been consistently undergoing physical therapy and taking medication, but there has been no improvement at all. Last night, he was crying and screaming because his groin was too painful. He said it doesn't hurt when he walks, but sitting is extremely painful and unbearable. Yesterday, perhaps due to the weather, he was especially in pain, so we applied cold compresses, gave him painkillers, and put him to sleep.

The hospital says there is nothing wrong, but should I undergo a detailed examination? It's really frustrating.

It's my son's leg, but why is it so swollen? ㅠㅠ

There is pain in the marked area, and when touched, it screams loudly.

 

*The term "o-geum" originally referred to the inner part of the arm or leg that bends, but generally, "o-geum" means the hollowed area behind a person's knee. In animals, this area is called the "dogani."

 

What is the cause of pain behind the knee in the popliteal area?

Baker's cyst is a condition in which the synovial membrane, which acts as a lubricant to allow the knee joint to move smoothly, breaks through the surrounding joint capsule due to various causes and forms a cyst.

A tear of the olfactory nerve is a condition in which the meniscus, a fibrous cartilage located between the thigh bone and the shinbone, tears, causing pain.

Spinal stenosis is a condition in which the spinal canal, the passage through which nerves pass at the back of the vertebrae, narrows due to various causes, compressing the nerves.

 

Other possible causes include anterior cruciate ligament injury, meniscal tear, and spinal problems.

 

Why is our little one's groin area hurting? Since he's a child practicing judo, I think it's important to find the cause and provide thorough treatment.

Please advise anyone who has experienced pain in the groin area.
