Respected Hazrat Hakeem sahab, Aslam-o-alaikum! I am sending an advice for the Ubqari readers, that if anyone benefits from it it will be a charity. It should be a years old pain not wound. Heat milk and add salt in an amount that the milk curdles and becomes of a kind of yogurt. Two or three times, put it on the area of pain and tie it. Inshallah you will feel relief. It is an experienced method.
