### Patient: Hello, I have been having a lot of pain and numbness in my back, legs and calves. The pain worsens when I walk or stand for too long. 
### Doctor: Based on your symptoms, you may be suffering from spinal stenosis. To confirm this, we need to conduct some medical tests. We will need to perform radiographic imaging procedures which will include X-rays, MRI scans, CT scans, and other diagnostic procedures such as an interview, evaluation, and consultation. Depending on the results, we may also recommend physical therapy exercises or insertion of a catheter or spinal stimulator and injection into the spinal canal to relieve your pain.
