Dear Doctor , My father is 68 yrs old and suffers from severe kind of leg pain. Both his legs got amputed from above knees, due to a train accident, 35 yrs back. He was on proxivon till now but, due to recent ban on that drug, its really hard for him to bear the pain. I was just wondering if, you can advise any other strong pain killer. He tried Ibuprofen, ponstan but not working really. Please advise me at mukherjee_83@hotmail.com Thanks Priya
