My Father-in-law, 74 years old is suffering from leg pain from past 3 months. Every thing is normal as per, General body checkup, blood test, X-ray, scanning and MRI(lower back, spinal cord). Doctor says he dont have any problem (we consulted 1 general physician and 2 orthopedic) and they gave him pain killer for 10 days. But he is still suffering from leg pain. Please guide me to help him to get rid of this leg pain. Thanks.Sri
