Dear Sir, My father who is 68 years old. Recently we took a MRI Scan for his spinal chord. His L4-L5 disc(above the abdomen) has been compressed to 6.5 mm. Other L2,L3....are 12mm or 11mm in width. His height:168 cms, age:68, weight:69. Please advice me on this. Is it better to go for a surgery or its curable by Physiotherapy treatment. Thanks, Saravana Perumal
