Hello!

The involvement of spinal nerves due to the stenosis you are facing is the reason of weakness in your upper and lower limbs.

If your cervical vertebrae are involved there can be issues with your fingers as the radial nerve, median nerve and ulnar nerve are main branches from brachial plexus from your cervical spine. Your lower spine problems in the lumbar vertebra cause problems in your legs.

Taking your age into consideration it is very difficult to suggest you any lifestyle changes. It is best to consider all options after your MRI. Follow the instructions of your neurosurgeon.

Take care!
