Little Problem

I am continuing to walk 5 miles per day.  I can no longer do it continuously without stopping to sit for a while.  It seems that I have a nerve condition that causes numbness in my upper left calf muscle.  After 2 to 3 miles it becomes painful.  Resting a few minutes gets the feeling back in my leg so I can continue walking.  I intend to see a doctor about it soon.  In the meantime I will go back to REI next week to purchase my pack and other equipment.
