My father is 41 years old and have spine pain from 4-5 years. Many doctors said that he is suffering from slip disc and 2 years ago a doctor said there is nothing to worry do simple exercise to remove the pain. Now my father everyday approx 2-4 km a day then too there is no change in the pain. What will be the best treatment according to you either he should take medicines or should go through a operation. And will operation be helpful? Please suggest.
