Patient: Hello, my friend started to have pain in his right leg above the knee in June last year, he was examined in several hospitals in Shanghai, the hospital did not take any film, said it was a muscle strain, let him go home and exercise himself, then he did not do any treatment, he has been taking painkillers, until he came home in February, he was examined by film and biopsy in his hometown, he was diagnosed with bone tumor, middle and late stage, there are metastasis in two points of waist 4 and chest 7. After a course of chemotherapy at the local hospital, he found that there was no effect and started to eat Chinese herbs and paste Chinese medicine at home until June, when he squatted too hard and the metastatic point in his lower back compressed the motor nerve, making his lower limbs numb and unable to move, he felt that he could not move and had difficulty in urinating. Doctor: If you have symptoms of nerve compression, surgery is the best way to go if the situation permits.
