Trauma is likely to cause bone tumors, pain is an important symptom of primary malignant bone tumors, pain is intermittent at first, and then develops into persistent, obvious at night, late pain worsens, affecting work, rest and sleep, requiring injection of strong analgesics. Benign bone tumors have a slow course and are painless or painless. The gradual growth of the mass is the basis for the diagnosis of many bone tumors.

Benign masses grow slowly and often go undetected, many patients are occasionally detected but cannot say when they begin to grow, the swollen mass has little effect on the surrounding tissues, and there is little impairment in joint mobility, mostly due to trauma radiographs. Malignant bone tumors grow rapidly and have a short course of disease, enlarged tumors can cause increased skin temperature and varicose veins, bone tumors located at the bony end of the long bone and metaphyseal can cause joint swelling and limited mobility, tumors located in the pelvis can cause constipation and dysuria, and chondroblastoma located in the long tubular epiphysis can cause joint swelling, effusion, erythrocyte sedimentation rate, and hemographic changes. Pathological fractures caused by minor trauma are often the first symptoms of benign bone tumors, and are also common complications of malignant bone tumors and bone metastases.

Either way, you must have an X-ray, or CT scan. I believe there is no big problem, and I wish you good health.

It should be a cyst. I used to have a fall while rollerblading, and I got a cyst on the outside.

Go take a picture to rule out bone lesions

Tibial tuberosity epiphysitis: the tibial tuberosity epiphysis is the insertion point of the patellar ligament and is a traction epiphysis. Due to the repeated and intense contraction of the quadriceps muscle, the slow-moving injury of the epiphysis at the epiphysis caused by parainflammation of the epiphysis, which caused avascular necrosis.

It is more common in patients with bilateral disease, and there are not many patients with bilateral disease. It is common in 10---15-year-old teenagers who love sports, and after the age of 20, the symptoms disappear because the ossification of the tibial tuberosity epiphysis fuses with the tibial tuberosity.

In case of pain, it can be applied externally with Osteosan**.

The pain of tibial tuberosity epiphysitis can persist for a long time, and the symptoms can disappear after ossification of the epiphysis, so it should be explained to the patient and his family to eliminate concerns and pay attention to prevention.

There are many causes of knee pain, such as bone hyperplasia and knee arthritis.

Opinions only old advice:

External factors such as wind chill can also cause symptoms. If the symptoms are severe, you can go to the hospital for examination.

Analysis: Hello, there is a bag in the knee, which is considered to be due to degeneration, the cartilondrium hyperplasia of the knee joint, resulting in the narrowing of the joint cavity, the occurrence of aseptic inflammation, and the excessive exudation of the synovium, forming a fibrous wrap leading to the occurrence of joint cysts.

Suggestions: It is recommended that with the enlargement of the cyst, it will cause symptoms of nerve and muscle compression, which will cause pain and affect the activity function of the limbs.
