Talk to Spine Specialist on Nerve Pressure

Asking for Someone Else, Sister, Female, 34 years old, Islamabad

Age: 34, Female No past history of accident/injury/fall, only light pain in left heel started 4 years ago while standing for long hours and left leg pain if doing heavy work for long hours or walk more than 5-6 km. The pain comes on and off. So the dr said to do the CT Scan. That's the CT scan of lumbar spine. Dr is saying for MRI and might need of surgery as lump is putting pressure on nerve. Is surgery really required in this case?
