Pain is a typical symptom of bone tumors. Especially when children have knee pain of unknown causes, or the pain cannot be relieved after resting for more than one week after minor injury, they should be alert to the possibility of malignant bone tumors.

Wei Xing, deputy chief physician of the PLA Orthopaedic Research Institute of the First Affiliated Hospital of the PLA General Hospital, said that bone tumors often occur in children around 10 years old, mostly in long tubular bones such as the femur, tibia, and humerus. The early symptoms are local pain, with varying degrees of pain, some only mild pain or discomfort, but children are likely to feel no pain because of pleasure when playing, When sleeping, I feel obvious pain, which is called "resting pain" in medicine.

With the progress of the disease, the pain becomes more and more severe, the pain part is fixed, and local swelling and skin temperature rise may also occur gradually. Some children are accompanied by fever, poor appetite, anemia and other symptoms.

It should be reminded that when a non bone tumor specialist receives a child with leg pain, if there is no abnormality in the ordinary X-ray film, he/she should be advised to return to the doctor or take MRI examination, so as not to delay treatment because of growth pain or soft tissue injury.
