Нужен when my uncle when my uncle was 65 years old he could not walk without a stick. his right leg hurt him very much. he consulted a doctor.the doctor examined him carefully. he sent sick patient to x-ray and when my uncle brought the x-ray picture the doctor gave hime heat treatment, massage and exercises twice or three times a week for three months. at the end of that time the doctor advised him to keep up the exercises every day. my uncle carried out all his instructions and the pain grew less and the old man could even walk without a stick.
